Subject: [PATCH 02/28] slot|signal: static_assert not using R,T... syntax

This can lead to clearer errors by explaining the user's error, not just
saying they used an incomplete type (why is it incomplete?). I don't use
only static_assert(false) because that's ill-formed before C++23, AFAIK,
& even if it's OK in some cases I don't grok which... so hope this works

+## Building the documentation
+
+The reference documentaion is built with Doxygen.
+
+The manual is a DocBook 5.0 document. These packages are recommended when building
+the manual (can have other names in other distros):
+ - docbook5-xml (Ubuntu and Debian) or docbook5-schemas (Fedora)
+ - docbook-xsl (Ubuntu and Debian) or docbook-style-xsl (Fedora)
+
+It may be possible to build without these packages, but it will be slow and error prone.
+The `xmllint` command is told to read files from http://docbook.org.
+The `xsltproc` command is told to read files from http://docbook.sourceforge.net.
+The commands first search for local copies of those files. If local copies exist
+and are installed at expected locations, the commands make no network accesses.

 ## Building from a release tarball
 
 Building from a release tarball is easier than building from git.

It's unnecessary when the meson version >= 0.58.
Simplify the calls to dependency().get_variable().

 functions or methods to signals

Those helper functions have 2 main usages:
* avoid writing template parameters in case of method or function overloading;
* wrap use of sigc::mem_fun or sigc::ptr_fun when possible.

unsupported cases:
* lambda functions;
* std::function (or alike);
* volatile functions;
* const? volatile methods;
* binding with sigc::bind.

Subject: [PATCH 17/28] signal_connect: Simplify ambiguity removal when
 compiling with MSVC

commented "const" in sigc::mem_fun prototypes' are meaningless. Using a
"const T_obj" as argument type when the method is const void any conflict.

remove useless struct in test program.

-
-2010-06-05  David King  <davidk@openismus.com>
-
-	Small website updates
-
-	* docs/index.html: Remove broken namespace links.
-	* docs/website/doc.shtml: Link to library.gnome.org tutorial and API
-	reference.
-
-2.2.8:
-
-2010-06-04  Murray Cumming  <murrayc@murrayc.com>
-
-	Manual: Add an id="index" attribute in case that helps library.gnome.org.
-
-	* docs/manual/libsigc_manual.xml: Add it to the <book> tag.
-
-2.2.7:
-
-2010-05-04  Murray Cumming  <murrayc@murrayc.com>
-
-	Documentation improvements.
-
-	* docs/manual/libsigc_manual.xml: Remove Marshallers section because
-	it is apparently outdated and there is no example code to test it.
-	This fixes bug #417924 (Michael Ekstrand)
-	* sigc++/sigc++.h: Main page text: Rearranged slightly.
-
-2010-04-27  David King  <davidk@openismus.com>
-
-	Improvements to main page documentation
-
-	* sigc++/sigc++.h: Minor improvements.
-
-2010-04-23  David King  <davidk@openismus.com>
-
-	Add main page to Doxygen documentation
-
-	* docs/Makefile.am: Parse sigc++/sigc++.h for documentation.
-	* sigc++/sigc++.h: Add main page to Doxygen documentation.
-
-2010-04-23  David King  <davidk@openismus.com>
-
-	Fix the functors Doxygen group in the m4 files
-
-	* sigc++/functors/macros/functor_trait.h.m4:
-	* sigc++/functors/macros/mem_fun.h.m4:
-	* sigc++/functors/macros/ptr_fun.h.m4: Rename functors to
-	sigcfunctors.
-
-2.2.6:
-
-2010-04-16  Murray Cumming  <murrayc@murrayc-desktop>
-
-	Docs: Fix the functors group and the link from the overview.
-
-	* docs/website/doc.shtml: Revert this to point to the overview page at
-    docs/indeex.html, which I have manually uploaded to the website, until
-    we add this overview to the doxygen-generated documentation itself.
-	* sigc++/functors/slot_base.h:
-	* sigc++/visit_each.h: Rename the functors doxygen group to sigcfunctors,
-    because doxygen seems to confuse it with the one in libstdc++.
-	* docs/index.html: Update the links.
-
-2010-04-16  Murray Cumming  <murrayc@murrayc.com>
-
-    Website: Fix the Makefile so upload works with sourceforge again.
-
-2010-04-06  Murray Cumming  <murrayc@murrayc.com>
-
-    Website: Update the reference API link.
-
-	* docs/website/doc.shtml: Update the reference API link to use
-    library.gnome.org. We should make sure that the tutorial docbook is there
-    too.
-    * docs/website/devel.shtml: Remove CVS-specific instructions, quickly
-    mentioning the git module instead.
-    However, the Makefile must be updated to cope with sourceforge's changes.
-    I was not able to upload this yet.
-
-2.2.5:
-
-2010-01-05  Daniel Elstner  <daniel.kitta@gmail.com>
-
-	Use non-blurry font for dot graph labels
-
-	* docs/reference/Doxyfile.in (SHOW_INCLUDE_FILES): Enable.
-	(SHOW_USED_FILES): Disable.
-	(DOT_FONTNAME): Change from FreeSans to Sans, as the hinting for the
-	former appears to be rather bad.
-	(TEMPLATE_RELATIONS): Disable to reduce noise.
-
-2009-12-29  Krzysztof Kosiński  <tweenk.pl@gmail.com>
-
-	Accumulators: Allow return types that are different to the signal's.
-
-	* sigc++/macros/signal.h.m4: signal_emit*: Correct the slot_iterator_buf_type
-	and slot_reverse_iterator_buf_type typedefs to allow accumulators with
-	return types that are different to the signal's return type.
-	* tests/Makefile.am: Reenable test_accumulated, so we can test the fix.
-	It should be manually disabled if building on AIX (if the AIX problem cannot
-	be fixed properly).
-	* tests/test_accumulated.cc: Add an accumulator with a return type that is
-	different to the signal's return type. In this case it's a vector listing
-	all results.
-	Bug #586436.
-
-2009-12-27  Daniel Elstner  <daniel.kitta@gmail.com>
-
-	Disable collaboration graphs in documentation
-
-	* docs/reference/Doxyfile.in (CLASS_DIAGRAMS): Enable.  Contrary to
-	what the Doxygen documentation says, no dot class inheritance graphs
-	will be generated if both CLASS_DIAGRAMS and COLLABORATION_GRAPH are
-	set to NO.
-	(COLLABORATION_GRAPH), (GROUP_GRAPHS): Turn off additional graphs to
-	reduce the noise.
-
-2009-10-26  Armin Burgmeier  <armin@arbur.net>
-
-	* sigc++config.h: Move the first five definitions to the !SIGC_MSC
-	ifdef block, so MSVC does not see them and only uses the definitions
-	from the SIGC_MSC block. This fixes the build with MSVC.
-
-2009-09-19  Daniel Elstner  <daniel.kitta@gmail.com>
-
-	Support Automake silent rules
-
-	* configure.ac: Call the AM_SILENT_RULES macro if it is defined.
-	* docs/doc-manual.am, sigc++/Makefile.am: Prefix the commands of
-	custom rules with $(AM_V_GEN) or $(AM_V_at) in order to support
-	the silent rules feature of Automake.
-
-2009-09-17  Michael Hasselmann  <michaelh@openismus.com>
-
-	Documentation cleanup: sigc::hide() always only hides one signal argument
-
-	* sigc++/adaptors/macros/hide.h.m4: The documentation stated that sigc::hide()
-	could discard multiple signal arguments when in fact the whole API only allows
-	control over one (dummy) signal argument at a time. The  "multiple argument
-	hiding" example lives in it own section now to make it clearer you have to nest
-	sigc::hide() for that.
-
-2009-09-13  Daniel Elstner  <daniel.kitta@gmail.com>
-
-	Enable verbose output of autoreconf
-
-	* autogen.sh: Pass --verbose option to autoreconf.
-
-2.2.4.2:
-
-2009-09-02  Daniel Elstner  <danielk@openismus.com>
-
-	Bump version to 2.2.4.2 and update NEWS
-
-	* configure.ac (AC_INIT): Increment version number to 2.2.4.2.
-	(MM_PREREQ): Require mm-common 0.7.2.
-	* NEWS: Write news entry for libsigc++ 2.2.4.2.
-
-2009-09-02  Daniel Elstner  <danielk@openismus.com>
-
-	Document namespace sigc briefly
-
-	* sigc++/signal_base.h (sigc): Prepend documentation comment to
-	provide a brief description of namespace sigc, so that Doxygen
-	will recognize the namespace as documented.
-
-2009-08-31  Daniel Elstner  <danielk@openismus.com>
-
-	Update Doxygen configuration for Doxygen 1.6.1
-
-	* docs/reference/Doxyfile.in: Update configuration template using
-	Doxygen 1.6.1.
-	(SORT_MEMBERS_CTORS_1ST): Enable.
-
-2009-08-31  Daniel Elstner  <danielk@openismus.com>
-
-	Protect space after comma in M4 output
-
-	* sigc++/macros/template.macros.m4 (_LOOP_SEP): Triple-quote the
-	list separator in this hairy construct, since the macro definition
-	itself is not quoted at all and the space after the comma got lost
-	in the output.  This, in turn, produced overlong lines in the HTML
-	reference documentation.
-
-2.2.4.1:
-
-2009-08-28  Daniel Elstner  <danielk@openismus.com>
-
-	Update news entry for libsigc++ 2.2.4.1 release
-
-	* NEWS: Update top entry for release 2.2.4.1 of libsigc++.
-	(2.2.4): Correct spelling of Frédéric Péters' name.
-
-2009-08-27  Daniel Elstner  <danielk@openismus.com>
-
-	Use shared mm-common Doxygen style sheet
-
-	* configure.ac (MM_PREREQ): Require mm-common 0.7.
-	* docs/Makefile.am (dist_noinst_DATA): List doxygen.css.
-	* docs/reference/Doxyfile.in (HTML_STYLESHEET): Assign path
-	to the shared doxygen.css provided by mm-common.
-
-2009-08-27  Daniel Elstner  <danielk@openismus.com>
-
-	Remove header and footer HTML fragments
-
-	* docs/reference/libsigc_{header,footer}.html_fragment: Delete
-	files.  These custom fragments were an unnecessary maintenance
-	hassle.  Also, the files were out of date with respect to the
-	encoding and CSS classes used by Doxygen.
-	* docs/reference/Doxyfile.in (HTML_HEADER), (HTML_FOOTER): Set
-	to the empty string.
-	(PROJECT_NAME): Substitute @PACKAGE_NAME@.
-	(PROJECT_NUMBER): Substitute @PACKAGE_VERSION@.  It does look
-	nicer in the generated HTML pages, and is probably also less
-	confusing.
-	(SORT_GROUP_NAMES): Enable for predictability.
-
-2009-08-26  Daniel Elstner  <danielk@openismus.com>
-
-	Bump version to 2.2.4.1 and update NEWS
-
-	* configure.ac (AC_INIT): Increment version number to 2.2.4.1.
-	* NEWS: Write news entry for libsigc++ 2.2.4.1.
-
-2009-08-26  Daniel Elstner  <danielk@openismus.com>
-
-	Reenable hierarchy graphs for each class
-
-	* docs/reference/Doxyfile.in (COLLABORATION_GRAPH): Set option
-	to YES to enable the per-class inheritance graphs.
-
-2009-08-25  Daniel Elstner  <danielk@openismus.com>
-
-	Have Automake check NEWS and use bzip2
-
-	* configure.ac (AM_INIT_AUTOMAKE): Add options check-news and
-	dist-bzip2.
-
-2009-08-25  Daniel Elstner  <danielk@openismus.com>
-
-	Update NEWS for libsigc++ 2.2.4 release
-
-2009-08-25  Daniel Elstner  <danielk@openismus.com>
-
-	Bump version to 2.2.4 and require mm-common 0.6.1
-
-	* configure.ac (AC_INIT): Increase version number to 2.2.4.
-	(MM_PREREQ): Require mm-common 0.6.1 for the updated default
-	location of the reference documentation.
-
-2009-08-25  Daniel Elstner  <danielk@openismus.com>
-
-	Change documentation host to library.gnome.org
-
-	* README, docs/manual/libsigc_manual.xml: Adjust links to the
-	reference documentation in the text.
-	* docs/Makefile.am (pubdocbase), (htmlrefpub): Remove override
-	and use the updated mm-common default values.
-	* sigc++{,-uninstalled}.pc.in (htmlrefpub): Adjust link.
-
-2009-08-24  Daniel Elstner  <danielk@openismus.com>
-
-	Add id="content" element to documentation index
-
-	* docs/reference/libsigc_header.html_fragment: Start <div> element
-	with attribute id="content" to match the other C++ binding modules.
-	* docs/reference/libsigc_footer.html_fragment: Close <div> element.
-
-2009-08-20  Daniel Elstner  <danielk@openismus.com>
-
-	Use new version component substitutions
-
-	* MSVC_Net200[58]/sigc.rc.in: Replace the no longer defined
-	@FP_*_VERSION@ substitutions by the new @SIGCXX_*_VERSION@
-	substitutions for the version number components.  These are
-	defined by MM_INIT_MODULE() from mm-common.
-
-2009-08-20  Daniel Elstner  <danielk@openismus.com>
-
-	Substitute API version in filenames dynamically
-
-	* sigc++.pc.in: Rename file from sigc++-2.0.pc.in.
-	* sigc++-uninstalled.pc.in: Rename file from
-	sigc++-2.0-uninstalled.pc.in.
-	* MSVC_Net200[58]/sigc.rc.in: Rename files from sigc-2.0.rc.in
-	and use @SIGCXX_API_VERSION@ substitution for the API version.
-	Also replace @VERSION@ with @PACKAGE_VERSION@.
-	* MSVC_Net200[58]/libsigc++2.{sln,vcproj}: Remove version from
-	the project name and filenames.
-	* MSVC_Net200[58]/filelist.am: Remove version from filenames.

-	names instead of hard-coding the API version.
-	* sigc++/Makefile.am (lib_LTLIBRARIES): Instead of hard-coding
-	the libtool archive name, substitute @SIGCXX_API_VERSION@ into
-	it, as well as into the derived variable names.
-
-2009-08-17  Daniel Elstner  <danielk@openismus.com>
-
-	Set libtool version information
-
-	* sigc++/Makefile.am (libsigc_2_0_la_LDFLAGS): Add libtool option
-	-version-info 0:0:0 to specify the version information explicitly.
-
-2009-08-16  Daniel Elstner  <daniel.kitta@gmail.com>
-
-	Remove unused parameter names for correctness
-
-	* tests/test_copy_invalid_slot.cc, tests/test_custom.cc,
-	tests/test_deduce_result_type.cc, tests/test_functor_trait.cc,
-	tests/test_limit_reference.cc: Remove the names of unused function
-	parameters from the prototype, in order to get libsigc++ to build
-	with fatal compiler warnings.
-
-2009-08-16  Daniel Elstner  <daniel.kitta@gmail.com>
-
-	Rename scripts/ to build/ for consistency
-
-	* build/: Rename directory from scripts/ for consistency with most
-	of the other modules that switched to the new build infrastructure.

-	Update for latest mm-common 0.4
-
-	* configure.ac (MM_PREREQ): Require mm-common 0.4.
-	(MM_INIT_MODULE): Omit now optional version number argument.
-	(MM_CONFIG_DOCTOOL_DIR): Copy the documentation utilities into docs/
-	instead of scripts/.
-	* Makefile.am (dist_noinst_DATA): Remove documentation utilities.
-	* sigc++-2.0.pc.in (htmlrefpub): Append trailing slash.
-	* sigc++-2.0-uninstalled.pc.in (htmlrefpub): ditto,
-	* docs/Makefile.am (htmlrefpub): ditto.
-	(doc_input): Perform a VPATH search for each input file, to correctly
-	handle the case of rebuilding the documentation of a tarball release
-	which includes the generated sources.
-	(dist_noinst_DATA): List documentation utilities.
-
-2009-08-11  Daniel Elstner  <danielk@openismus.com>
-
-	Do not recurse into MSVC subdirectories
-
-	* MSVC_Net200[58]/filelist.am: New Automake include files, defining
-	the lists of files to ship from the MSVC project directories.
-	* MSVC_Net200[58]/Makefile.am: Delete recursive Makefile.am files.

-	* configure.ac (AC_CONFIG_FILES): Remove the output files
-	MSVC_Net200[58]/Makefile.am from the list.
-	(AC_CONFIG_COMMANDS): Copy sigc++config.h into the MSVC project
-	directories at the end of config.status.
-
-2009-08-11  Daniel Elstner  <danielk@openismus.com>
-
-	Remove now superfluous doctool overrides
-
-	* docs/Makefile.am: Remove overrides for the documentation
-	utilities, since MM_CONFIG_DOCTOOL_DIR() already takes care
-	of setting MMDOCTOOLDIR to the local directory.
-	* sigc++-2.0.pc.in (datadir): Substitute value, just in case.
-
-2009-08-10  Daniel Elstner  <danielk@openismus.com>
-
-	Have mm-common-prepare install the doc utils
-
-	* configure.ac: Call MM_CONFIG_DOCTOOL_DIR([scripts]) to set
-	up the destination directory for mm-common-prepare to copy
-	the documentation utilities to.
-	* scripts/doc-install.pl: Delete file.

-	* scripts/tagfile-to-devhelp2.xsl: ditto.

-	$(PERL) interpreter command in front of the script name.
-
-2009-08-08  Daniel Elstner  <danielk@openismus.com>
-
-	Disable extraction of undocumented identifiers
-
-	* docs/reference/Doxyfile.in (EXTRACT_ALL): Change setting to
-	NO, and adapt a number of related options accordingly.  The
-	result is a net loss of about 300 generated .html files.  The
-	roughly 450 files which remain now are still an insanely high
-	number, though.
-	(PREDEFINED): Predefine the Autoconf configuration defines to
-	nudge Doxygen towards documenting the canonical code paths.
-
-2009-08-07  Daniel Elstner  <danielk@openismus.com>
-
-	Use #error explicitly instead of broken code
-
-	* sigc++config.h.in: Do use the #error preprocessor directive,
-	instead of an errornous piece of code.  This code does not need
-	the same level of obfuscation as an Autoconf feature test.
-
-2009-08-07  Daniel Elstner  <danielk@openismus.com>
-
-	Change bug report URL to point to Bugzilla
-
-	* configure.ac (AC_INIT): Change the bug-report argument to the
-	URL for filing a new libsigc++ bug on bugzilla.gnome.org.  Also
-	name the website URL as fifth argument.  It will simply be ignored
-	if the installed Autoconf does not support this new feature.
-
-2009-08-07  Daniel Elstner  <danielk@openismus.com>
-
-	Do not enable -pedantic mode by default
-
-	* configure.ac (MM_ARG_ENABLE_WARNINGS): Remove -pedantic from the
-	list of compiler flags to use at warning level "min" (the default).
-
-2009-08-07  Daniel Elstner  <danielk@openismus.com>
-
-	Correct M4 forbidden tokens pattern
-
-	* configure.ac (m4_pattern_forbid): Take into account that the
-	pattern is applied to tokens, not lines.  Also catch unexpanded
-	calls to underscore-prefixed private macros.
-
-2009-08-06  Daniel Elstner  <danielk@openismus.com>
-
-	Transition to new mm-common build infrastructure
-

-2.2.3:
-
-2008-10-08  Armin Burgmeier  <armin@arbur.net>
-
-	* MSVN_Net2005/libsigc++2.vcproj: Changed output name to match the new
-	naming convention.
-
-	* MSVC_Net2008/: Added MSVC 2008 project files. These are basically
-	the same as for MSVC 2005, but converted to MSVC 2008 projects.

-	by default.
-
-	* MSVC_Net2005/libsigc++2.vcproj: Renamed the generated debug database
-	file to sigc-2.0d.pdb (the default), to stay consistent with the *mm
-	wrapper libraries.
-
-2008-08-08  Armin Burgmeier  <armin@arbur.net>

-	* MSVC_Net2005/libsigc++2.sln:
-	* MSVC_Net2005/libsigc++2.vcproj:
-	* MSVC_Net2005/tests/*/*.vcproj: Converted the Visual Studio 2003
-	project files to 2005 ones.
-
-	* MSVC_Net2005/Makefile.am:
-	* Makefile.am:
-	* configure.ac: Adapted build files accordingly.
-
-2008-04-06 Cedric Gustin <cedric.gustin@gmail.com>
-
-	* MSVC_Net2003/sigc-2.0.rc.in: Removed ATL/MFC header files
-	dependency as afxres.h is not part of the Microsoft Platform
-	SDK provided with Visual C++ Express 2008.
-	Bug #503933.
-
-2.2.2:
-
-2008-03-10  Deng Xiyue  <manphiz@gmail.com
-
-	* sigc++/macros/slot.h.m4:
-	Added an include of functors/slot.h that was mistakenly removed
-	during the 2.1 series, apparently breaking API slightly.
-	Bug #521418.
-
-2.2.1:
-
-2008-02-28  Elaine Xiong  <elaine.xiong@sun.com>
-
-	* sigc++/macros/signal.h.m4:
-	* tests/test_accum_iter.cc: Add ifdefs around uses of

-	Bug #302098.
-
-2.2.0:
-
-2008-01-01  Ryan Hill  <dirtyepic@gentoo.>
-
-	* tests/test_copy_invalid_slot.cc: Include the cstdlib
-	and cstring headers to fix the build with the gcc 4.3
-	pre-release. Bug #454882.
-
-2007-08-31  Murray Cumming  <murrayc@murrayc.com>
-
-	* tests/test_copy_invalid_slot.cc: Added some includes to

-
-2.1.1:
-
-2007-08-14  Murray Cumming  <murrayc@murrayc.com>

-	* sigc++/macros/signal.h.m4:
-	* sigc++/macros/slot.h.m4:
-	* sigc++/object.h:
-	* sigc++/retype_return.h: Removed deprecated
-	compatibility API, to probably fix the build with
-	some compilers, such as some versions of the Sun Forte C++
-	CC compiler. Some of these headers are now mostly empty and
-	should be removed later.
-	This API has been deprecated April 2004, and
-	is not widely used, so it seems safe to do this now.
-
-	* tests/Makefile.am:
-	* tests/test_compatibility.cc: Removed this test.
-
-2007-07-28  Michael Elkstrand  <michael@elehack.net>
-
-	* sigc++/macros/signal.h.m4: slot_iterator_buf,
-	slot_reverse_iterator_buf: Added typedefs for
-	value_type, reference, and pointer, so that these
-	iterators are more like standard C++ iterators, so they can
-	be used with standard C++ algorithms.
-	* tests/Makefile.am:
-	* tests/test_accum_iter.cc: Added a test for this.
-	Bug #417926.
-
-2006-11-14  Daniel Elstner  <daniel.kitta@gmail.com>
-
-	* autogen.sh: Wholly replace this script with a critter from one
-	of my personal projects, with slight modifications.  This one does
-	some sophisticated stuff like probing version numbers of available
-	automake and aclocal executables, in order to choose the right one
-	accordingly.  All this is necessary to make the build system work
-	robustly in custom environments such as Maemo where automake-1.9
-	doesn't come preinstalled.

-
-2005-12-01  Murray Cumming <murrayc@murrayc.com>
-
-	* sigc++/functors/slot_base.cc:
-	slot_base::disconnect(): Set call_ to 0,
-	to invalidate the slot, even if parent_ is 0.
-	I think parent_ is, for instance, a signal, but
-	disconnect should still work on a slot that is not
-	connected to a signal, because a slot can be invoked

-
-2005-07-09  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/macros/signal.h.m4: slot_iterator:

-
-2.0.15:
-
-2005-07-04  Philip Langdale  <plangdale@vmware.com>
-
-	* sigc++/adaptors/macros/compose.h.m4: Add a setter typedef to
-	compose*_functor and use it instead of the (incorrect) getter
-	typedef in the compose* specialization of visit_each<>().
-	This corrects the lifetime management of slots created with

-
-	* sigc++/type_traits.h: Define SIGC_WRAP_IS_BASE_CLASS_ based on

-
-2005-06-07  Murray Cumming <murrayc@murrayc.com>

-
-2005-05-16  Neal E. Coombes  <nealc@trdlnk.com>
-
-	* sigc++/signal_base.h:  Modified temp_slot_list to be a temporary view
-	into a slot list.  Instead of emptying the original it now simply tacks
-	a placeholder to the end of the original.  It then uses this as it's
-	'end' iterator.  This should allow for conscious recursiveness, as well
-	as inserting a slot to any position in the slot list during emittion.
-	See bug #303896.
-
-2005-06-04  Friedemann Kleint <kleint@bifab.de>
-
-	* sigc++/macros/limit_reference.h.m4:
-	visit_each() template specializations:

-	Forte 5.5.
-
-2.0.12:
-
-2005-05-06  Régis Duchesne <hpreg@vmware.com>
-
-	* sigc++/macros/limit_reference.h.m4 (added):
-	* sigc++/Makefile.am:
-	New class that just stores a reference, and makes sure that if the
-	reference derives from trackable, then the trackable reference will be
-	used instead of the derived reference in visit_each().
-	* sigc++/functors/macros/mem_fun.h.m4: Better fix for bug #169225 by
-	Régis Duchesne and Christian Hammond, based on the new limit_reference
-	class.
-	* sigc++/adaptors/bound_argument.h (added): New class (built upon the
-	new limit_reference class) that handles all 3 kinds of bound arguments:
-	by value, by reference, and by constant reference. References are
-	unwrapped in the bound_argument's constructor.
-	* sigc++/adaptors/macros/bind.h.m4: Fix for bug #302327 by Régis
-	Duchesne. Bound arguments now need to know whether they are passed by
-	reference or not. So bind() now builds bind_functor instances using
-	'reference_wrapper<Foo>' types, instead of 'Foo &' types. The
-	bind_functor code is modified to compensate.
-	* sigc++/adaptors/macros/bind_return.h.m4: Similar fix for a similar
-	bug (unfiled) with bound return arguments.
-	* sigc++/reference_wrapper.h:
-	* sigc++/type_traits.h:
-	The reference_wrapper class is only used in bound_argument.h. Put
-	correct but unused code under #if 0.
-	* sigc++/adaptors/lambda/base.h: This file needs reference_wrapper.h,
-	but was incorrectly relying on type_traits.h to include it.
-	* tests/Makefile.am:
-	* tests/test_virtualbase_delete.cc (deleted):
-	* tests/test_virtualbase_delete_ref_param.cc (deleted):
-	* tests/test_limit_reference.cc (added):
-	Replaced test_virtualbase_delete*.cc with a simpler
-	test_limit_reference.cc which checks for all 3 aspects of the same bug
-	in one file.
-	* tests/test_bind_ref.cc: Slots must use 'Foo &' types. We were lucky
-	this broken usage worked before this change. The change in
-	type_traits.h made this bug obvious, by preventing the code to compile.
-	* tests/test_bind_return.cc: After my change, bind() and bind_return()
-	must use 'reference_wrapper<Foo>' types.
-	* tests/test_custom.cc: Made this test a no-op (so it does not perturb
-	'make check' on released versions of the library) and made it a
-	template ready to be modified by hackers.
-
-2005-05-01  Murray Cumming <murrayc@murrayc.com>
-
-	* sigc++/functors/slot_base.cc:
-	slot_base::slot_base(src): If the source
-	slot_base has a null rep->call_, meaning that the
-	slot is invalid, just return a default-constructed
-	slot, to prevent the crash shown in
-	tests/tests_copy_invalid_slot.cc. Bug #302515 by
-	Régis Duchesne.
-
-2005-05-01  Murray Cumming <murrayc@murrayc.com>
-
-	* sigc++/functors/macros/mem_fun.h.m4: bound_*<>:
-	Add a new is_base_and_derived<sigc::trackable>
-	parameter to the template and thereby provide a
-	specialization for T_Obj types that derive from
-	sigc::trackable. This prevents a crash when casting
-	from the derived type to sigc::trackable after the
-	derived destructor has run. This cast can sometimes
-	fail when using multiple inheritance, at least with
-	g++. Bug #169225 by Régis Duchesne and Christian
-	Hammond.
-	* sigc++/type_traits.h: Add documenation for
-	the internal is_base_and_derived<> template, which
-	allows us to specialize other templates for certain
-	template types.
-
-2005-04-28  Murray Cumming <murrayc@murrayc.com>
-
-	* sigc++/type_traits.h: Added comments for users of

-
-2005-04-28  Murray Cumming <murrayc@murrayc.com>
-
-	* tests/Makefile.am:
-	* tests/test_virtualbase_delete.cc: Added
-	simplified test case from bug #169225. We have a patch
-	to make this succeed but I am not ready to commit it
-	just yet.
-
-2005-04-27  Murray Cumming <murrayc@murrayc.com>
-
-	* tests/Makefile.am:
-	* tests/test_custom.cc:
-	Added a place to put extra test code, so I don't have
-	to keep installing my crazy libsigc++ versions.
-
-2005-04-27  Murray Cumming <murrayc@murrayc.com>
-
-	* sigc++/visit_each.h: Revert back to the non-explicit
-	template call, because we can not specify the
-	template specialization so easily, because the
-	specializations have different numbers of types.
-	* tests/Makefile/am:
-	* tests/test_bind_ref.cc: Add a simple test only for
-	sigc::ref disconnection.
-
-2005-04-26  Murray Cumming <murrayc@murrayc.com>
-
-	* sigc++/visit_each.h: Use the explicit template
-	specialization, needed for Tru64 and AIX compilers.
-	This causes a crash in some uses of sigc::ref()
-        (when using g++ 3.3.4 or 3.3.5 , but not with 3.4) but
-	seems to fix a crash in some uses of multiple inheritance
-	(bug #169225).
-	* tests/test_bind.cc: Comment out the crashing (not with
-	g++ 3.4) use of sigc::ref() with an explanatory comment.

-2005-03-09  Cedric Gustin <cedric.gustin@swing.be>
-
-	* Makefile.am: Moved MSVC_Net2003 directory to SUBDIRS.
-	* MSVC_Net2003/Makefile.am: Added blank.cpp to EXTRA_DIST.
-	* MSVC_Net2003/libsigc++2_msvcNet2003.sln: Removed
-	test_accumulated and test_lambda projects as the tests are
-	disabled in the standard, configure-based build.
-	* MSVC_Net2003/MSVC_Net2003/libsigc++2_msvcNet2003.vcproj:
-	Generate a PDB file in the Debug target.

-
-2005-02-20  Martin Schulze  <mschulze@cvs.gnome.org>

-2005-02-11  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* docs/manual/Makefile.am: Set the correct group in post-html.
-
-2005-02-11  Murray Cumming  <murrayc@murrayc.com>
-
-	* docs/website/doc.shtml: Fix typo in url for reference docs. Found by
-	James Lin.
-
-2005-02-06  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/signal_base.h: temp_slot_list::begin(), end(): Actually
-	return the iterators.
-
-2005-02-03  Neal E. Coombes <nealc@trdlnk.com>
-
-	* sigc++/signal_base.h: Add temp_slot_list struct to facilitate
-	allowing new connections to a signal during an emittion without
-	affecting that emittion.
-	* sigc++/macros/signal.h.m4: Use the new struct temp_slot_list to
-	prevent connections made during an emittion from being called in the
-	same emittion (which has the potential of causing things like
-	infinite loops).  This guarantees an emittion will be finite, as well
-	as maintaining any order of emittion guarantees that may have already
-	been in place.
-
-2.0.9:
-
-2005-02-02  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/visit_each.h: visit_each_type(): Reverted the change, so that
-	we do not specify the template types ot visit_each<>(), because it
-	crashes on g++ 3.3.4 (but not g++ 3.4.2). Added a comment telling users
-	of AIX (and maybe IRIX MipsPro and Tru64) to use the alternative version
-	if they have compilation problems.
-
-2005-02-01  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/adapators/macros/base.h.m4: Add sigc::var<>() documentation,
-	from Roger Ferrer Ibáñez in bug #149483.
-
-2005-02-01  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/adaptors/macros/compose.h.m4: In the template specializations
-	of visit_each(): As before, specify the specific other template
-	specializations of visit_each that we use. Needed by AIX.
-	* tests/Makefile.am: Reenabled most tests, because AIX can now
-	build them.
-
-2005-02-01  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/visit_each.h: visit_each_type(): Specify the specific
-	template specialization of visit_each<>() to use. The AIX compiler,
-	and possibly the Tru64 compiler, need this extra hint.
-
-2005-02-01  Murray Cumming  <murrayc@murrayc.com>
-
-	* bind.h.m4: Define bind_functor::operator() inline because the AIX
-	compiler/linker sometimes fails to find it when it is defined
-	outside of the class.
-
-2.0.8:
-
-2005-01-30  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/type_traits.h: is_base_and_derived: Added
-	avoid_gcc3_warning_(), to avoid an incorrect warning when using
-	g++ 3.3.5
-
-2005-01-28  Liza Klerck   <liza@trdlnk.com>
-
-	* sigc++/functors/macros/mem_fun.h.m4: Add a sigc:: namespace
-	prefix to the nested use of visit_each(), to avoid ambiguity when
-	using 2 versions of the libsigc++ API inside different namespace.
-
-2005-01-27  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/adaptors/macros/adaptor_trait.h.m4: Add a sigc:: namespace
-	prefix to the nested use of visit_each(), to avoid ambiguity when
-	using 2 versions of the libsigc++ API inside different namespace,
-	which is not very advisable anyway. Bug #165222 from
-	liza at trdlnk.com.
-
-2.0.7:
-
-2005-01-24  Cedric Gustin <cedric.gustin@swing.be>
-
-	* sigc++config.h.in : Moved the SIGC_USING_STD macro definition
-	out of the SIGC_CONFIGURE section. We also need it for MSVC.
-	* MSVC_Net2003/.cvsignore : Added .def and .aps files
-	* MSVC_Net2003/Makefile.am: Rewrote rule for local copy of
-	sigc++config.h (required for 'make distcheck').
-	* MSVC_Net2003/libsigc++2_msvcNet2003.sln: Added test_retype and
-	test_disconnect_during_emit tests.
-	* MSVC_Net2003/tests/test_disconnect_during_emit/*,
-	MSVC_Net2003/tests/test_retype/*: Initial commit.
-
-2005-01-21  Murray Cumming  <murrayc@murrayc.com>
-
-	* tests/: Disabled the test_accumulator, test_bind, and test_compose
-	tests, and part of test_mem_fun because the AIX xlC compiler can not
-	build them, but it can still do most things, including the examples.
-	See the comments in tests/Makefile.am.
-
-2005-01-21  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/adaptors/bind.h.m4: non-member operator()(): Specify the
-	extra nil arguments in the templated class name prefix. Oddly, the
-	AIX xlC compiler says that the type of the first parameter does not
-	match the template if you don't do this.
-
-2005-01-21  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/type_traits.h: is_base_and_derived struct: Move the
-	is_base_class_() functions out of the inner class, because the AIX
-	xlC compiler does not like that - see the comments in the code.
-	* sigc++/adaptors/bind.h.m4: Add the extra nil template types to
-	the template specializations, as in slot and signal.
-
-2005-01-21  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/functors/macros/slot.h.m4, sigc++/macros/signal.h.m4:
-	slot and signal template specialization for
-	various numbers of template args: In the class slot line, specify
-	all the remaining template types as null, instead of expecting the
-	compiler to guess them in itself. This partly fixes the build on
-	AIX with the xlC compiler. Bug #164685.
-
-2005-01-19  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/type_traits: struct is_base_and_derived: Make the test inner
-	struct a friend, so that it can use the big inner struct. This is
-	required by the Tru64 compiler.
-	* sigc++/adaptors/lambda/base.h: Put the unwrap_lambda_value()
-	definitions at the top, because Tru64 (understandably) needs them to
-	be declared before use.
-
-2005-01-19  Murray Cumming  <murrayc@murrayc.com>
-
-	* scripts/: Added cxx_std.m4, with a test copied from
-	glibmm/scripts/cxx_std.m4 to check if the compiler has the std::
-	namespace.
-	* sigcconfig.h: #undef the new #define and add SIGC_USING_STD(),
-	like GLIBMM_USING_STD, to put stuff in the std:: namespace when it
-	is not there already,
-	* configure.in: Used the new test.
-	* tests/*: Uses SIG_USING_STD() for every std:: thing that we use.
-	This is needed by the Tru64 and HP-UX compilers when using their
-	defaults.
-
-2005-01-19  Murray Cumming  <murrayc@murrayc.com>
-
-	* configure.in: AC_INIT(): Provide the extra tarball name parameter,
-	so that it does not create a libsigc--- tarball.
-
-2005-01-19  Murray Cumming  <murrayc@murrayc.com>
-
-	* configure.in: AC_INIT(): Use libsigc++ instead of sigc++, attempting
-	to get the correct tarball name.
-
-2005-01-18  Murray Cumming  <murrayc@murrayc.com>
-
-	* configure.in: Used the autoconf 2.93 and AM_INIT_AUTOMAKE()
-	technique to specify ustar format for the tarball, to prevent files
-	with long file names from appearing at the top of the tarball.
-	Based on the same fix in gtkmm 2.6.
-
-2005-01-18  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/functors/macros/slot_h.m4: Specify the base class when
-	using the rep_ member variable. This stops the HP-UX aCC compiler
-	from saying that a Nonstatic member  is referenced in a nested class,
-	local class or static member initializer. Bug #150719.
-
-2005-01-18  Murray Cumming  <murrayc@murrayc.com>
-
-	* Bug #159597 - patch from e97_far at e.kth.se to replace C-style
-	casts with reinterpret_cast<> and static_cast<> to avoid warnings.
-
-2005-01-17  Murray Cumming  <murrayc@murrayc.com>
-
-	* docs/manual/Makefile.am: Specifying html/index.html instead of
-	just the html directory as a target seems to fix distcheck problems.
-	I can also now confirm that the install works on solaris, when using
-	gmake, though not when using make.
-
-2005-01-17  Murray Cumming  <murrayc@murrayc.com>
-
-	* MSVC_Net2004/Makefile.am: Add built files to DISTCLEANFILES to fix
-	the distcheck.
-	* docs/reference/Makefile.am, manual/Makefile.am: Specify $srcdir in
-	paths, to fix distcheck of the manual, and maybe fix install problems
-	on Solaris.
-
-2005-01-11  Murray Cumming  <murrayc@murrayc.com>
-
-	* docs/website/stable.html: Updated the text about binary packages.
-	* docs/website/docs.html: Link to the 2.0 documentation instead of the
-	1.2 documentation.
-
-2004-12-17  GregSchussman  <schussman@slac.stanford.edu>
-
- 	* glossary.shtml: Clean up punctuation, make definitions complete
-        sentences, and add clarifications for certain definitions according to
-        what Murray Cumming's suggestions and answers to my questions.
- 	Bug #161580.
-
-2005-01-11  Murray Cumming  <murrayc@murrayc.com>
-
-	* docs/: Added manual, copied from the libsigc++-1.2 cvs module,
-	and updated it for the new 2.0 API.
-
-2005-01-11  Murray Cumming  <murrayc@murrayc.com>
-
-	* docs/: Added website, copied from the libsigc++-1.2 cvs module.
-	We will use it from here from now on.
-
-2004-12-11  Cedric Gustin <cedric.gustin@swing.be>
-
-	* configure.ac : parse version tags at configure time (for
-	sigc-2.0.rc).
-	* MSVC_Net2003/sigc-2.0.rc.in : New resource file.
-	* MSVC_Net2003/Makefile.am: include sigc-2.0.rc in distribution.
-
-2004-12-08  Cedric Gustin <cedric.gustin@swing.be>
-
-	* MSVC_Net2003/Makefile.am: get sigc++config.h from $(top_builddir)
-	instead of $(top_srcdir).
-
-2004-12-08  Cedric Gustin <cedric.gustin@swing.be>
-
-	* MSVC_Net2003/*/*.vcproj: Renamed libsigc++ target to
-	sigc-2.0d.dll (Debug) and sigc-2.0.dll (Release). Added
-	$(SolutionDir) and $(SolutionDir)\.. to "Additional Include
-	Directories" in tests projects.
-	* sigc++config.h.in: Rewrote dllexport/dllimport macros for
-	MSVC, for better consistency with glibmm/gtkmm.
-	* MSVC_Net2003/Makefile.am: copy sigc++config.h from $(top_srcdir)
-	at build time.
-
-2004-11-27  Murray Cumming  <murrayc@murrayc.com>
-
-	* configure.in: Revert the AC_PROG_LIBTOOL change, so that this builds
-	with actually released libtool versions, and in jhbuild, so that it
-	gets testing.
-
-2004-11-06  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* sigc++/adaptors/macros/exception_catch.h.m4: Make catcher_ member
-	public so that it can be accessed by visit_each() (bug reported on
-	ml by Philip Langdale <plangdale@vmware.com>).
-
-2004-10-24  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* MSVC_Net2003/*/*.vcproj: Link with the "multithreaded DLL" runtime
-	libraries and enable RTTI for the MSVC build
-	(patch from Timothy M. Shead <tshead@k-3d.com>).
-	* MSVC_Net2003/*/.cvsignore: Hide generated build files from cvs
-	(patch from Timothy M. Shead <tshead@k-3d.com>).
-
-2.0.6:
-
-2004-10-12  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* MSVC_Net2003/*/*.vcproj, MSVC_Net2003/blank.cpp: Fix project files
-	to compile out-of-the-box and add dummy file so that .cc files get
-	recognized as c++ code files (patch from Timothy M. Shead).
-
-2004-10-10  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* sigc++/signal_base.{h,cc}, sigc++/functors/slot_base.{h,cc},
-	sigc++/functors/macros/slot.h.m4: If SIGC_NEW_DELETE_IN_LIBRARY_ONLY
-	is defined, implement signal_base::operator new/delete and
-	slot_rep::operator new/delete (suggested by Timothy M. Shead).
-	Remove old work-around from 2004-10-02 since it didn't work.
-
-2004-10-07  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* configure.ac: Update for libtool 1.5a (with support for Intel C++).
-	* MSVC_Net2003/sigc++config.h: Remove bogus '#define'
-	(reported by Timothy M. Shead <tshead@k-3d.com>).
-
-2004-10-02  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* configure.ac: Bump version number to 2.0.6.
-	* NEWS: Add ChangeLog summary for version 2.0.6.
-
-2004-10-02  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* sigc++/functors/slot_base.{h,cc}, sigc++/functors/macros/slot.h.m4:
-	Rename (typed_)slot_rep::detach to (typed_)slot_rep::destroy.
-	Call the dtor of the functor stored in typed_slot_rep from destroy().
-	A cleaner solution would be to add an additional "virtual" function
-	that calls 'delete' or a real virtual dtor. However, this would be
-	less efficient and might break the ABI. (Fixes #152323.)
-
-2004-10-02  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* sigc++config.h.in, MSVC_Net2003/sigc++config.h,
-	sigc++/signal_base.cc, sigc++/functors/slot_base.{h,cc},
-	sigc++/functors/macros/slot.h.m4: Define and use new macro
-	SIGC_NEW_DELETE_IN_LIBRARY_ONLY to ABI-compatibly move
-	all calls to new and delete into non-inline library code.
-
-2004-09-26  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* sigc++/adaptors/lambda/macros/group.h.m4: Add a missing
-	template keyword in the definition of deduce_result_type::type
-	(hopefully fixes #152327).
-
-2004-09-26  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* sigc++/macros/object_slot.h.m4: Use correct bound_mem_functor
-	variants for const (volatile) methods (fixes #148744).
-
-2004-09-01  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* docs/index.html: Correct link to lambda module.
-
-2004-09-01  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* README: Update compatibility section.
-
-2.0.5:
-
-2004-09-01  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* MSVC_Net2003/Makefile.am: Add sigc++config.h to EXTRA_DIST.
-	* configure.ac: Bump version number to 2.0.5.
-	* NEWS: Add ChangeLog summary for version 2.0.5.
-
-2.0.4:
-
-2004-08-21  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* tests/test_lambda.cc: Use sigc::var("\n") instead of sigc::ref("\n").
-	Comment out the affected lines, nevertheless.
-	Sun FORTE and Compaq C++ can handle neither sigc::ref("\n") nor
-	sigc::var("\n"). I see more chances fixing sigc::var("\n").
-	* sigc++/adaptors/lambda/macros/base.h.m4: Add a comment about a
-	possible work around for sigc::var("\n") compiler problems.
-	* tests/test_compatibility.cc: Remove a 'const' keyword that prevents
-	the test case from compiling with the Sun FORTE.
-	* tests/test_trackable.cc: Remove a 'virtual' keyword and an unused
-	variable to avoid compiler warnings.
-	* NEWS: Add ChangeLog summary for version 2.0.4.
-
-2004-08-03  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* scripts/cxx.m4, sigc++config.h.in, configure.ac,
-	sigc++/adaptors/lambda/macros/operator.h.m4, tests/test_lambda.cc:
-	Rollback change from 2004-07-15: configure check
-	SIGC_OPERATOR_OVERLOAD_AMBIGUITY is not needed - the overload
-	ambiguity doesn't occur if the lambda operators take all arguments
-	as const reference.
-	* configure.ac: Bump version number to 2.0.4.
-
-2004-08-03  James Lin <slimjimmy@mail.com>
-
-	* Added SIGC_API qualifier to all externally-visible non-template
-	classes/structs.
-	* Added #include <sigc++config.h> to the files that use SIGC_API.
-	* Added empty SIGC_API definition to sigc++config.h.in for non-MSVC
-	compilers.  I'm not sure if this is the right place to put this
-	(probably not).
-	* Added MSVC-specific sigc++config.h to the MSVC project directory.
-	(The comment in it probably should be edited.)
-	* Changed MSVC project settings to output a multi-threaded DLL, set
-	the include paths to work (hopefully) out-of-the-box.  Disabled
-	precompiled headers, since they just complicate things and
-	shouldn't be necessary for such a relatively project.
-
-2004-08-01  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* sigc++/type_traits.h: Remove type_trait<>::instance()
-	(was unimplemented and unused; caused problems with the MSVC).
-
-2004-07-23  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* Makefile.am: Fix typo concerning distribution of libsigc++-2.0.spec.
-	* AUTHORS: Mention our contributors for platforms Sun FORTE and Intel C++.
-
-2004-07-15  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* *.h.m4: Don't call operator()() in sun_forte_workaround(); rather copy
-	operator()(). Calling operator()() makes a copy of the arguments causing
-	wrong results if an argument type is a reference. Hopefully fixes #147311.
-
-2004-07-15  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* tests/test_lambda.cc: Break "std::cout << [expr] << a << std::endl;"
-	into "std::cout << [expr]; std::cout << a << std::endl;".
-	I hope this fixes #147313 where the right values for "[expr]" but wrong
-	values for "a" were written to std::cout for some compiler with optimizations
-	turned off.
-
-2004-07-15  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* sigc++/adaptors/lambda/macros/operator.h.m4: Correct return type deduction
-	of lambda expressions in lambda_operator*::operator()(). Might be related to
-	bug #147313.
-	* sigc++/adaptors/lambda/macros/group.h.m4: Use m4 macro _P_().
-
-2004-07-15  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* scripts/cxx.m4, sigc++config.h.in, configure.ac,
-	sigc++/adaptors/lambda/macros/operator.h.m4, tests/test_lambda.cc:
-	Add configure check SIGC_OPERATOR_OVERLOAD_AMBIGUITY for a SUN FORTE
-	compiler problem (bug #147391). Use it to decide whether the lambda
-	action operators may be overloaded (not doing so restricts the API slightly).
-	* sigc++/adaptors/lambda/macros/operator.h.m4: Add some doxygen comments
-	and remove attic code.
-	* sigc++/adaptors/lambda/macros/base.h.m4:
-	Add templates unwrap_lambda_type and unwrap_lambda_value() to support
-	the non-overloaded lambda action operators. Also add some doxygen comments
-	and remove attic code.
-	* sigc++/adaptors/lambda/macros/group.h.m4: Fix a bug that resulted in
-	gargabe values being passed on to the functor contained in the group adaptor
-	(partly fixes #147313).
-
-2004-07-11  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* scripts/cxx.m4, sigc++config.h.in, configure.ac, *.h.m4:
-	Split SIGC_CXX_TEMPLATE_SPECIALIZATION_OPERATOR_OVERLOAD
-	into SIGC_CXX_GCC_TEMPLATE_SPECIALIZATION_OPERATOR_OVERLOAD
-	and SIGC_CXX_MSVC_TEMPLATE_SPECIALIZATION_OPERATOR_OVERLOAD.
-	Remove LIBSIGC_TEMPLATE_PREFIX. Add template keyword to
-	SIGC_WORKAROUND_OPERATOR_PARENTHESES depending on the configure checks.
-	Should fix the compiler problems with MSVC.
-
-2004-07-11  Martin Schulze <mschulze@cvs.gnome.org>
-
-	* examples/hello_world.cc: Use sigc::ptr_fun instead of std::ptr_fun.
-	(fixes bug #144846)
-
-2004-07-11  Eric Bourque <ericb@computer.org>
-
-	* libsigc++-2.0.spec.in: new file
-	* configure.ac : patched generate spec file
-	* .cvsignore: ignore generated file (Martin Schulze)
-	* Makefile.am: distribute spec file (Martin Schulze)
-
-2004-07-11  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/connection.cc: Added some comments.
-	* sigc++/trackable.cc: operator=(): Check for self-asignment, though I
-	do not know of any actual bug that this fixes. Added some comments.
-	* sigc++/trackable.h Added some doxygen documentation.
-
-2004-07-09  Murray Cumming  <murrayc@murrayc.com>
-
-	* tests/: Added test_disconnect_during_emit.cc, to prove that this
-	works.
-
-2004-07-08  Murray Cumming  <murrayc@murrayc.com>
-
-	* tests/test_retype_return.cc: foo::operator(int): return a
-	value. The SUN Forte 5.5 compiler complains about this, as it should.
-
-2004-07-08  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/macros/signal.h.m4: class signal*: Rename the slot_list
-	typedef to slot_list_type, because there is already a template class
-	called slot_type. SUN Forte 5.5 seems to complain about this and I am
-	not surprised. The old typdef is still there for backwards
-	compatibility, except when building with SUN Forte.
-
-2004-07-07  Murray Cumming  <murrayc@murrayc.com>
-
-	* scripts/cxx.m4: SIGC_CXX_TEMPLATE_SPECIALIZATION_OPERATOR_OVERLOAD():
-	Don't define the SIGC_TEMPLATE_SPECIALIZATOIN_OPERATOR_OVERLOAD C
-	macro at all if the test fails. This might fix the build on SUN Forte.
-	* sigc++/functors/macros/mem_fun.h.m4: Default constructor: Initialize
-	the func_ptr_ member variable. I have no evidence that this solves any
-	problems, but it worried me.
-	* sigc++/functors/slot_base.h: operator bool(): Correct documentation,
-	to use @code instead of <code>
-	* sigc++/macros/signal.h.m4: Remove the documentation for the
-	parameters named first and last, because they do not exist.
-
-2004-05-31  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* autogen.sh: Add '--force'-flag to the 'libtoolize'-command (bug #143425).
-
-2.0.3:
-
-2004-05-30  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* configure.ac: Bump version number to 2.0.3.
-	* NEWS: Add ChangeLog summary for version 2.0.3.
-	* sigc++/macros/signal.h.m4: Fix segfault on emission of unconnected signal.
-	* tests/test_signal.cc, tests/test_accumulated.cc: Emit unconnected signal.
-	* sigc++/macros/object_slot.h.m4: Suppress compiler warning at
-	dynamic_cast<>-test (tested by Christof Petig/Timothy M. Shead).
-
-2.0.2:
-
-2004-05-22  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* configure.ac: Bump version number to 2.0.2.
-	* NEWS: Add ChangeLog summary for version 2.0.2.
-
-2004-05-20  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* sigc++/macros/signal.h.m4: If a custom accumulator is specified
-	invoke it on signal emission even if the signal's slot list is empty.
-	(This used to be the case in libsigc++-1.2 as pointed out by Timothy.)
-
-2004-05-20  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* sigc++/macros/object_slot.h.m4: Suppress compiler warning at
-	dynamic_cast<>-test (suggested by Timothy M. Shead).
-
-2004-05-01  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* README: Updated for libsigc++-2.0.
-
-2.0.1:
-
-2004-04-27  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* configure.ac: Bump version number to 2.0.1.
-	* NEWS: Add ChangeLog summary for version 2.0.1.
-	* sigc++/adaptors/lambda/macros/base.h.m4: Fixed documentation.
-	* sigc++/adaptors/macros/bind.h.m4: Hide work-arounds from doxygen.
-	* scripts/cxx.m4, sigc++config.h.in, configure.ac,
-	sigc++/adaptors/macros/bind.h.m4: Removed configure	check. It
-	showed that the Apple gcc can also compile the sophisticated version
-	of the work-around.
-
-2004-04-26  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* sigc++/macros/object_slot.h.m4: Modified test for SigC::Object
-	inheritance so that it also works if SigC::Object is virtual base.
-	(Fixes bug 141094 reported by Jonathan Brandmeyer)
-
-2004-04-26  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* scripts/cxx.m4: Updated the configure check. It would probably
-	have succeeded on the Apple.
-
-2004-04-26  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* sigc++/adaptors/macros/bind.h.m4: Add work-arounds for
-	bind<-1>::deduce_result_type compilation error on Apple gcc 3.3.
-	* scripts/cxx.m4, sigc++config.h.in, configure.ac: Add configure
-	check for the compilation error above.
-	* sigc++/adaptors/lambda/macros/operator.h.m4: Replace _A with
-	_Aa. _A is a reserved keyword on Apple gcc 3.3 (Spundun Bhatt).
-	(fixes bug #10444 reported by Spundun Bhatt)
-
-2004-04-19  Martin Schulze  <mschulze@cvs.gnome.org>
-
-  * sigc++/signal_base.cc: Fixed serious bug in signal_base::impl():
-  Only reference a newly created object (initial reference).
-  (This fixes bug #140269 reported by Andris.)
-
-2004-04-19  Murray Cumming  <murrayc@murrayc.com>
-
-	* scripts/cxx.m4: Updated the operator() template check, because it
-	failed with gcc 3.4 (from cvs). Apparently the template keyword can
-	only be used from another template.
-
-2.0.0:
-
-2004-04-06  Martin Schulze  <mschulze@cvs.gnome.org>
-
-	* configure.ac: Bump version number to 2.0.0.
-	* NEWS: Add ChangeLog summary for version 2.0.0.
-	* TODO, AUTHORS: Bring up to date.
-	* sigc++-2.0.pc.in, Makefile.am: 1.9 -> 2.0
-	* Added more documentation.
-
-2004-04-10  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/connection.[h|cc]: Implement blocked() to avoid undefined
-	symbol linker error.
-
-2004-04-08  Murray Cumming  <murrayc@murrayc.com>
-
-	* dist the scripts directory.
-
-1.9.16:
-
-2004-04-06  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* configure.ac: Bump version number to 1.9.16.
-	* NEWS: Add ChangeLog summary for version 1.9.16.
-
-2004-04-02  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++/connection.cc: Make block() and unblock() always return a
-	value, to fix compiler warnings. Patch from bug #138620 by
-	Alexander Nedotsukov.
-
-2004-04-02  Murray Cumming  <murrayc@murrayc.com>
-
-	* Fix the compile of examples/member_method.cc. Bug #131701 from
-	Kirill Smelkov. I also made the examples build as part of the regular
-	build.
-
-2004-04-02  Murray Cumming  <murrayc@murrayc.com>
-
-	* sigc++config.h.m4: Remove every undef apart from the one we need, to
-	avoid clashes, because we #include this in a public header.
-
-2004-03-25  Murray Cumming  <murrayc@murrayc.com>
-
-	* scripts/cxx.m4, configure.in, sigc++config.h.in: Rename the
-	template_keyword check to template_specialization, because the problem
-	is with or without the keyword.
-	* sigc++/adaptors/macros/adaptor_trait.h.m4: Define
-	SIGC_WORKAROUND_OPERATOR_PARENTHESES, which calls either operator() or
-	sun_forte_workaround() depending on the result of the compiler test.
-	* many .m4 files: Add sun_forte_workaround methods that call the
-	operator() methods. Put them in #ifdefs so that only SUN Forte C++
-	sees them.
-
-2004-03-22  Murray Cumming  <murrayc@murrayc.com>
-
-	* Makefile.am, sigc++/Makfile.am: Fix the sigc++config.h.in disting,
-	to fix make distcheck.
-
-2004-03-21  Murray Cumming  <murrayc@murrayc.com>
-
-	* Rename config.h.in to sigc++config.h.in so that gtkmm does not
-	include some other config.h at strange times - fixes a problem in
-	the gtkmm demos. This should really be in the sigc++ directory, but
-	that seems to add that as an include path, which causes the STL
-	headers to include sigc++/signal.h instead of some STL signal.h header.
-
-2004-03-20  Murray Cumming  <murrayc@murrayc.com>
-
-	* Makefile.am: Install the config.h platform-specific header.
-	* sigc++-2.0.pc.in: Report the include path for config.h
-
-2004-03-20  Murray Cumming  <murrayc@murrayc.com>
-
-	* Added config.h.in, using autoheader, from which config.h will be
-	generated, so we can detect compiler features.
-	* configure.ac: Added AC_CONFIG_HEADER(config.h) to generate config.h
-	from config.h.in.
-	* scripts/cxx.m4: Added this directory and file, with a
-	SIGC_CXX_TEMPLATE_KEYWORD_OPERATOR_OVERLOAD macro that defines
-	the SIGC_TEMPLATE_KEYWORD_OPERATOR_OVERLOAD C macro.
-	* autogen.sh: Added -I scripts to the aclocal call, so that it finds
-	the m4 macro for configure.ac.
-	* sigc++/adapators/macros/adaptor_trait.h.m4: Include config.h and
-	use SIGC_TEMPLATE_KEYOWRD_OPERATOR_OVERLOAD.
-
-2004-03-18  Martin Schulze  <mschulze@cvs.gnome.org>
-
-  * tests/test_mem_fun.cc, tests/test_ptr_fun.cc: Don't test
-  making functors from overloaded methods with partial template
-  specialization. Not portable among different compilers (SUN FORTE).
-  * adaptors/macros/apdaptor_trait.h.m4: Only gcc seems to use the
-  notation A.template operator()<...>(...) => adapt preprocessor check
-  for #define LIBSIGC_TEMPLATE_PREFIX. TODO: replace with configure check.
-
-2004-03-13  Murray Cumming  <murrayc@murrayc.com>
-
-	* g++ 3.4 (pre-release) build fixes:
-	* sigc++/macros/signal.h.m4: slot_iterator_buf::operator*():
-	Use blocked() and empty() instead of non-existant blocked_and_empty().
-	* sigc++/functors/macros/mem_fun.h.m4: memfun_functor*::operator()():
-	Use this->func_ptr_ instead of just func_ptr_.
-	* sigc++/adaptors/macros/deduce_result_type.h.m4: Use
-	T_functor::template deduce_result_type<> instead of just
-	T_functor::deduce_result_type<>.
-	* sigc++/adaptors/lambda/macros/base.h.m4, operator.h.m4, group.h.m4::
-	Use template keyword again. operator[](): Use this->value_ instead of
-	just value_.
-	* sigc++/adaptors/lambda/macros/bind/m4: Use template keyword, and
-	this-> again.
-	* sigc++/adaptors/macros/compose.h.m4, hide.h.m4, bind_return.h.m4,
-	exception_catch.h.m4:
-	rettype.h.m4, rettype_return.h.m4: Use template keyword,and this-> again
-
-1.9.15:
-
-2004-02-27  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* configure.ac: Bump version number to 1.9.15.
-	* NEWS: Add ChangeLog summary for version 1.9.15.
-
-2004-02-27  Martin Schulze  <teebaum@cvs.gnome.org>
-
-  * sigc++/functors/macros/slot.h.m4: Make the unnumbered slot templates'
-  copy ctors use the copy ctors of the base class. Fixes bug #24698.

-2004-02-19  Martin Schulze  <teebaum@cvs.gnome.org>
-
-  * sigc++/type_traits.h: Make is_base_and_derived<> platform independant.
-  * sigc++/adaptors/lambda/macros/base.h.m4: Make lambda_core<> ctors
-  explicit. Remove an unused ctor from lambda_core<T_type, true>.
-
-2004-02-14  Martin Schulze  <teebaum@cvs.gnome.org>
-
-  * sigc++/functors/slot_base.h, sigc++/functors/macros/slot.h.m4:

-
-2004-02-13  Murray Cumming  <murrayc@usa.net>
-
-	* sigc++/functors/slot_base.[h|cc], sigc++/trackable.[h|cc]: Create
-	and use a typedef for the destroy_notify callback functions, to avoid
-	confusion function pointer declaration syntax in the API.
-
-2004-02-13  Murray Cumming  <murrayc@murrayc.com>
-
-	* Moved implementation to .cc files:
-	* sigc++/functors/: Added slot_base.[h|cc] which contains non-template

-	the .cc file.
-	* sigc++/functors/macros/slot.m4: Removed the code that has been moved
-	to slot_base.[h|cc].
-	* sigc++/: Added signal_base.[h|cc] which contains non-template code
-	that was previously in the generated signal.h and non-generated

-
-	* sigc++/adaptors/macros/[bind,hide].h.m4: Change to zero-based
-	argument index in numbered bind() and hide() overload
-	(Agreement on the mailing list).

-
-	* sigc++/macros/signal.h.m4: Document accumulators.
-	Move slot_iterator_buf into namespace internal. Since
-	accumulators have the iterator type as a template argument
-	there is no need to expose this very internal type.
-	* sigc++/functors/macros/*.m4: Regroup documentation.
-	Documentation of the core parts of the library should be
-	complete by now.

-	match std::mem_fun_t and to be more consistent with adaptors.
-	- Use ::sigc::slot's implicit ctor in compatibility module.
-	* sigc++/adaptors/lambda/operator.h.m4: Change some

-
-	* sigc++/retype.h.m4: Use LIBSIGC_TEMPLATE_PREFIX
-	in explicit function template instantiations.
-	* sigc++/type_traits.h: Add template specialization
-	for arrays (T_type[N]) to disable non-working member
-	type_trait<T_type[N]>::instance().
-	* sigc++/visit_each.h: Remove more disturbing
-	limit_derived_target<>::operator() overloads.
-	(Should have noticed earlier that they are unnecessary.)
-	* sigc++/adaptors/deduce_result_type.h.m4,
-	sigc++/adaptors/lambda/operator.h.m4,
-	sigc++/functors/functor_trait.h.m4,
-	tests/test_[bind,compose,exception_catch,hide,lambda].cc:
-	Completely removed support for typeof(). We don't need

-
-2003-10-30  Cedric Gustin <cedric.gustin@swing.be>
-
- 	* configure.ac: Added test of win32 platform. Commented

-	Use LIBSIGC_TEMPLATE_PREFIX in explicit function
-	template instantiations.
-	* sigc++/tests/test_*.cc:

-2003-10-26  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	Fixes:
-	* sigc++/functors/slot.{cc,h.m4}:
-	- Fix notification process: don't defer detaching of a
-	slot from all referred trackables during signal emission!
-	- Size optimization: replace virtual functions from

-
-2003-09-10  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/adaptors/lambda/{base,operators}.h.m4:
-	Add subscript ([]) and assign (=) operator. I think there are now
-	enough operators available to make any future power user happy.
-	The only one missing is the comma operator and if we added it
-	the logical consequence would be to also add if(), switch(), do(),
-	etc. lambda expressions which are really out of place in libsigc++.
-	* sigc++/type_traits.h: Fix is_base_and_derived<> for const types.
-	* tests/test_lambda.cc: Test new operators.
-
-1.9.7:
-
-2003-09-05  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* configure.ac: Bump version number to 1.9.7.
-
-2003-09-03  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/adaptors/lambda/operator.h.m4:
-	- Restructure so that the size of the generated source file stays
-	reasonable for 34 operators: There are only two lambda templates
-	lambda_operator and lambda_operator_unary. The action is an additional
-	template parameter. A small template lambda_action[_unary] is specialized
-	for all actions.
-	- Add most operators that boost::lambda supports. Missing operators are
-	"=", "[]", "," and support for pointer arithmetic. I don't know if it's
-	worth adding these. In libsigc++, the purpose of lambda operators is to
-	provide some extra functionality for the group adaptor.
-	* tests/test_lambda.cc:
-	Test pre-increment, address and dereference operator.
-
-2003-08-31  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/reference_wrapper.h, sigc++/type_traits.h, sigc++/Makefile.am:
-	New file reference_wrapper.h provides ref() to specify that adaptors/lambdas
-	should take a reference to the object passed into ref() instead of a copy.
-	* tests/test_lambda.cc:
-	- Test group() with mem_fun().
-	- Use ref() where lambdas should store references to objects.
-	- Test var() and constant().
-	* sigc++/adaptors/lambda/base.h.m4:
-	- Support ref() in return type deduction.
-	- Add var() and constant() which create lambdas for usage with lambda operators.
-	* sigc++/adaptors/lambda/operator.h.m4:
-	- Fix return type deduction.
-	- Remove operator{+,-,*,...} overloads added on 2003-08-29. ref() is way cleaner.
-	* sigc++/adaptors/lambda/group.h.m4,
-	sigc++/adaptors/bind.h.m4, sigc++/adaptors/compose.h.m4,
-	sigc++/adaptors/exception_catch.h.m4, sigc++/adaptors/hide.h.m4:
-	Fix return type deduction.
-
-2003-08-29  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* tests/test_lambda.cc: Add more tests.
-	* sigc++/adaptors/lambda/select.h.m4, sigc++/adaptors/lambda/lambda.cc.m4:
-	Make _1, _2, ... constant.
-	* sigc++/adaptors/lambda/operator.h.m4:
-	Add operator{+,-,*,...} overloads to distinguish between const and non-const objects.
-	Store references to non-const objects rather than copies.
-	This allows expressions like e.g. std::cout << _1.
-	* sigc++/adaptors/lambda/base.h.m4, sigc++/adaptors/lambda/group.h.m4:
-	Remove void specializations. Functors returning void are tested and work fine.
-
-2003-08-27  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* tests/test_callof.cc, tests/test_deduce_result_type.cc:
-	Rename, correct and improve this test case.
-	* tests/Makefile.am: Build and run test_deduce_result_type
-	instead of test_callof.
-
-2003-08-27  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* Update TODO.
-
-2003-08-27  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/adaptors/hide.h.m4: Remove usage of callof_ignore_arg<>.
-	* sigc++/callof.h.m4, sigc++/adaptors/deduce_result_type.h.m4,
-	sigc++/functors/functor_trait.h.m4:
-	Remove the first and move deduce_result_type templates from
-	functor_trait.h.m4 into new file deduce_result_type.h.m4.
-	* sigc++/Makefile.am, sigc++/sigc++.h, sigc++/adaptors/adaptor_trait.h.m4:
-	Build and include sigc++/adaptors/deduce_result_type.h instead of callof.h.
-	* sigc++/functors/slot.h.m4: Document struct nil.
-
-2003-08-24  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/functors/functor_trait.h.m4: Simplify usage of convenience
-	macro SIGC_FUNCTORS_HAVE_RESULT_TYPE:
-	namespace sigc{ namespace functor{ SIGC_FUNCTORS_HAVE_RESULT_TYPE }}
-
-2003-08-24  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/functors/functor_trait.h,m4, sigc++/adaptors[/lambda]/*.h.m4:
-	Merge adaptor return type deduction and typeof() into
-	sigc::functor::deduce_result_type. Use it for all adaptors.
-	* tests/test_compose.cc: Only test multi-type get-functor if
-	typeof() if supported.
-
-2003-08-24  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/adaptors[/lambda]/*.h.m4:
-	- Remove unnecessary void specializations. In fact, only the one
-	for sigc::functor::exception_catch<> is needed and I don't really
-	understand why. For the lambda stuff the void specializatoins are
-	just commented out at the moment.
-	- Make typeof() optional. Surprisingly, I got the lambda stuff working
-	without typeof()! The test suite doesn't catch all cases yet, so maybe
-	some thing are still not working.
-	TODO: Implement configure check.
-	* tests/test_bind.cc, tests/test_compose.cc tests/test_exception_catch.cc,
-	tests/test_hide.cc, tests/test_lambda.cc:
-	Only test multiple functor return types if typeof() is supported.
-
-2003-08-06  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/trackable.{cc,h}: Add function trackable::clear().
-
-2003-06-24  Andreas Rottmann  <rottmann@users.sourceforge.net>
-
-	* TODO: Minor tweaks.
-
-2003-06-23  Andreas Rottmann  <rottmann@users.sourceforge.net>
-
-	* docs/reference/Doxyfile.in: Use these variables.
-	* docs/reference/Makefile.am (html/index.html): Provide doxygen
-	with SRCDIR and TOP_SRCDIR environment variables.
-
-	* sigc++/functors/slot.h.m4: Make slot::call_type typedef public;
-	this fixes a g++ 3.3 error in signal.h.
-
-	* sigc++/signal.h.m4: Make the signal::accumulated class public;
-	this fixes a g++ 3.3 error in test_accumulated.cc.
-
-2003-06-15  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/functor/slot.h.m4: Correct typing error in docs.
-	* sigc++/functor/ptr_fun.h.m4: Document the whole thing.
-
-2003-05-31  Murray Cumming  <murrayc@usa.net>
-
-	* Reference documentation: Rearranged the groups to make it all
-	a bit more like the libsigc++ 1.2 reference documentation.
-	Corrected some spelling and grammar too.
-	This needs a lot of work. The text is very hard to read and it's
-	generally not appropriate for a user of the code who doesn't
-	care about the internals. But it's not impossible - our examples
-	should show us what we need to say in the documentation.
-	We probably need some more groups for the extra stuff, like we do
-	in libsigc++ 1.2.
-
-2003-05-29  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/signal.h.m4: Fix documentation.
-	* sigc++/connection.h, sigc++/functor/slot.h.m4:
-	Document the whole thing.
-
-2003-05-29  Martin Schulze  <teebaum@cvs.gnome.org>
-
-	* sigc++/signal.h.m4:
-	- Remove bogus operator() from unnumbered signal<> and
-	  signal<>::accumulated templates.
-	- Document the whole thing.
-
-	* docs/index.html: Fix some links.
-
-2003-04-06  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* TODO, configure.ac, Makefile.am, docs/*:
-	Add Doxygen framework.
-
-2003-04-06  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/callof.h.m4, sigc++/adaptors/*, tests/test_callof.cc:
-	Move sigc::callof<> to sigc::functor::internal::callof<>.
-
-	* sigc++/functors/mem_fun.h.m4, tests/test_mem_fun.cc:
-	Add new types [bound_][const_]volatile_mem_functor, visit_each()
-	and mem_fun() overloads for volatile qualifier.
-	Add ctor overloads in bound_*mem_functor and mem_fun() overloads
-	that take reference instead of pointer.
-
-2003-03-26  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* Change "closure" to "slot" throughout sigc++2 (file names,
-	class names, member variables, documentation, etc.).
-
-2003-03-26  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* TODO: Rewrite to reflect recent changes as well as recent discussions.
-
-2003-03-24  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/adaptors/bind_return.h.m4: Make the adaptor's data member
-	public so that visit_each() can access it.
-
-	* sigc++/adaptors/lambda/*.h.m4: More fixes. Add a note about
-	malfunctioning typeof() (probably compiler bug in gcc-3.2).
-
-	* tests/*.cc: Test references. Fix compose equivalent in test_lambda.
-
-2003-03-24  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/Makefile.am, sigc++/functors/functor_trait.h[.m4],
-	sigc++/adaptors/adaptor_trait.h.m4: Move detection of function
-	and member method pointers' return types from adaptor_trait into
-	functor_trait. (We'll use functor_trait rather than adaptor_trait for
-	our lambda stuff.) functor_trait.h needs to be generated from .m4 now.
-
-	* sigc++/functors/functor_trait.h.m4: Add convenience macros:
-	- SIGC_FUNCTORS_HAVE_RESULT_TYPE indicates that the existance of
-	T_functor::result_type should be assumed for all unknown functors.
-	- SIGC_FUNCTOR_TRAIT(T_functor, T_result) explicitly specifies the
-	result type of a functor.
-	("typename functor_trait<T_functor>::result_type") is used to
-	determine the return type of our adaptors' operator()() overloads.
-
-	* sigc++/adaptors/[lambda/]*.h.m4: Various fixes in visit_each() and
-	operator()() overloads to make these operator()() overloads usable.
-	Most of them were just commented out before. Some adaptor types also
-	have void specializations, now.
-
-	* sigc++/adaptors/lambda/group.h.m4: Change syntax from
-	"[some_functor] % grp([args])" to "group([some_functor], [args])"
-	like we agreed on the ml some time ago.
-
-	* sigc++/tests/test_[all adaptors].cc: Test stuff that didn't work
-	before.
-
-2003-03-22  Murray Cumming  <murrayc@usa.net>
-
-	* Added pgk-config file, from a mystery person in bug #108857
-
-2003-03-22  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* tests/test_bind.cc: Test and show how to use functor_trait
-	for user defined or 3rd-party functors so that a
-	bind<0>([functor],[arg1])() call with no arguments can return a value.
-
-2003-03-20  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/callof.h.m4: Add explanations. Comment in / create templates
-	callof_safe[#]. Unfortunately they don't work for functors with overloaded
-	operator() so we don't use it for now. At least everything is documented.
-
-	* sigc++/functors/functor_trait.h, sigc++/functors/*.h.m4: Add back
-	functor_base compiler hint. We're using it now in adaptor_functor<>.
-
-	* sigc++/adaptors/{adaptor_trait,bind}.h.m4: Make operator() overloads
-	with no arguments return the result of the functor invocation.
-	Fix multiple bind<0>().
-	* tests/test_bind.cc: Test the stuff that's working now.
-
-2003-03-16  Murray Cumming  <murrayc@usa.net>
-
-	* Added sigc++/sigc++.h, like in libsigc++ 1.2
-	* examples: Added member_method example, which uses a class method
-	and which demonstrates disconnection.
-
-1.9.6:
-
-2003-03-11  Andreas Rottmann  <rottmann@users.sourceforge.net>
-
-	* sigc++/Makefile.am: Use substitution references instead of
-	$(patsubst). Is shorter and fixes the strange-dirs-in-dist-tarball
-	bug.
-
-2003-03-09  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/connection.h: Add block() capability.
-
-2003-03-09  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/signal.{cc,h.m4}: Add flag signal_impl::destroy_
-	and function signal_impl::destroy(). Use them to defer
-	the destruction of the signal_impl object during signal
-	emission.
-
-	* tests/test_disconnect.cc: Add tests for the connection
-	class and for deleting signals during emission.
-
-2003-03-09  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/connection.{cc,h}, sigc++/Makefile.am:
-	- New files that add a connection class. Objects of this
-	  class are constructed from closure list iterators and can
-	  be used to disconnect the refered closure. As opposed to
-	  iterators they stay valid beyond the lifetime of the closure.
-
-2003-03-09  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/functors/closure.{cc,h.m4}, sigc++/signal.cc:
-	- Rename closure_{base,rep}::[set_]dependency_ -> [set_]parent_.
-	- Make closure_rep inherit trackable. This allows for
-	  connection objects that stay valid beyond the life time
-	  of the refered closure.
-	- Make some one-line-functions inline again.
-
-2003-03-08  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/trackable.cc: BUGFIX in trackable_dep_list::clear()
-
-2003-03-08  Andreas Rottmann  <rottmann@users.sourceforge.net>
-
-	* sigc++/Makefile.am: Rewritten so we can build lambda cleanly.
-	* sigc++/Makefile.am_fragment: Removed.
-
-	* sigc++/functors/Makfile.am: Removed.
-	* sigc++/adaptors/Makefile.am: Removed.
-	* sigc++/adaptors/lambda/Makefile.am: Removed.
-	* configure.ac (AC_OUTPUT): Remove the above Makefiles.
-
-	* tests/Makefile.am: Re-included lambda test.
-
-2003-03-07  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/signal.{cc,h.m4}:
-	- signal_emit#<>: New templates replacing signal#<>::caller.
-	  The purpose of these templates is implementing the emit
-	  function and optimizing signal emission for the case that
-	  no accumulator is used via template specializations.
-	- default_accumulator<>: Removed. The default for T_accumulator
-	  in signal#<> now is nil. An example how to use accumulators
-	  is available in tests/test_accumulator.cc.
-	- signal_{base,impl}: Move the implementation of signal_base's
-	  interface to signal_impl. An object of this class is
-	  dynamically allocated when first connecting a closure to
-	  the signal. This drastically reduces the size of empty signals
-	  and allows for future addition of a reference counter to make
-	  it safe to delete a signal during emission.
-	- Directly work on closure_rep during signal emission. This
-	  seems to be quicker than using the closure templates.
-	- Document the classes. Restructure the header file a bit.
-
-	* sigc++/functors/closure.h.m4: Make closure_base::rep_ data
-	member public, so that signal emission can directly work on it.
-
-	* tests/test_size.cc: Add an entry for signal_impl.
-
-2003-03-07  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/functors/closure.{cc,h.m4}:
-	- closure_base: BUGFIXES in ~closure_base() and operator=().
-	- Mark some functions with the inline keyword. This seems to
-          help gcc 3.2 to optimize signal emission and (dis)connection.
-	- Document the classes. Restructure the header file a bit.
-
-2003-03-07  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/trackable.{cc,h}: Make trackable allocate a
-	trackable_dep_list object dynamically when adding the first
-	dependency. (This reduces the size of objects, that are not
-	refered by a closure by 4 bytes (50%) and increases the size
-	of objects that are refered by a closure by 4 bytes (50%)
-	on a 32 bit architecture => This reduces total memory use
-	when >50% of the trackables are not refered by a closure.)
-	Document the classes.
-
-2003-03-05  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* tests/Makefile.am, tests/test_size.cc, tests/test_accumulated.cc:
-	Add two test cases. test_size is showing the size of  public and
-	internal structures. (Which apart from empty signals are smaller
-	than the sizes of the equivalent libsigc++-1.2 structures.)
-	test_accumulated is a test for the template signal<>::accumulated<>
-	at the same time showing the use of accumulators in libsigc++2.
-
-	* Offtopic: My note about binary sizes from 2003-02-10 is wrong.
-	Stripped libsigc++2 test binaries are about 8-10k in size.
-
-2003-03-05  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/visit_each.h: BUGFIX in template specialization
-	limit_derive_target<T_Target*,T_action>::with_type<false,T_type>:
-	Add non-const overloads for static void execute_() avoiding
-	compile time errors.
-
-2003-02-16  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* tests/Makefile.am, tests/test_disconnect.cc:
-	Add testcase with a mixed connection & disconnection sequence.
-
-2003-02-16  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/signal.cc: Bugfix in signal_base::insert():
-	Set notification function in the newly created copy of
-	slot_ rather than in slot_ itself.
-
-2003-02-10  Martin Schulze  <MHL.Schulze@t-online.de>
-
-	* sigc++/signal.h.m4: Comment in typedefs for iterator types in
-	the signal#<> class template. Make signal#<>::connect() return an
-	iterator for convenience.
-	(Note that the first change increases the binary size of
-	tests/test_signal from 201k to 204k, the second change to 206k.)
-
-2003-01-23  Murray Cumming  <murrayc@usa.net>
-
-	* sigc++/adaptors/lambda is disable temporarily (not built and
-	not distributed) because it gets built before its parent
-	directory, but #includes generated sources in the parent directory.
-
-2003-01-22  Murray Cumming  <murrayc@usa.net>
-
-	* Added Andreas Rottman's example.
-
-2003-01-22  Murray Cumming  <murrayc@usa.net>
-
-	* Applied Andreas Rottman's make dist fixes.
-
-2003-01-14  Murray Cumming  <murrayc@usa.net>
-
-	* Added whitespace to make the code more readable.

Subject: [PATCH 27/28] Meson build: Better detection of MSVC-like compilers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Treat all compilers with MSVC-like argument syntax the same.
Use cpp_compiler.get_define('_MSC_VER') instead of
cpp_compiler.version() to check compiler version.
Suggested by Tim-Philipp Müller and Chun-wei Fan.

See https://gitlab.freedesktop.org/cairo/cairomm/-/merge_requests/30
