The C compiler needs to be told what calling-conventions to use when
compiling the Fortran interface for the UDUNITS package.

If you will not use the Fortran interface, then it will not matter what
conventions you specify and the following should work:

    1.  Go to the top-level source-directory.

    2.  Perform steps 3 through 5, described near the end of the file
        INSTALL.

    3.  Ensure that the environment variable CPPFLAGS contains the string
        "-Df2cFortran", e.g.,

            export CPPFLAGS=-Df2cFortran

        or

            setenv CPPFLAGS -Df2cFortran

    4.  Perform steps 6 through 9, described near the end of the file
        INSTALL.

If, however, you will use the Fortran interface, then the CPPFLAGS 
environment variable must define a specific C-macro that depends on the
Fortran compiler that you will use.  Examples for specific Fortran
compilers can be found in the file INSTALL.
