# The environment variables CC, GCC, LDFLAGS, LD, with_gnu_ld

# should be set by the caller.

#

# The set of defined variables is at the end of this script.

# Known limitations:

# - On IRIX 6.5 with CC="cc", the run time search patch must not be longer

# than 256 bytes, otherwise the compiler driver will dump core. The only

# known workaround is to choose shorter directory names for the build

# directory and/or the installation directory.

# All known linkers require a `.a' archive for static linking (except M$VC,

# which needs '.lib').
