-dnl Author: Franc,ois Pinard
-dnl
-dnl Synopsis: AC_PROG_CC_STDC
-dnl
-dnl Arguments: ---
-dnl
-dnl Use: If the C compiler in not in ANSI C mode by default, try to
-dnl add an option to output variable `CC' to make it so. This
-dnl macro tries various options that select ANSI C on some system
-dnl or another. It considers the compiler to be in ANSI C mode
-dnl if it defines `__STDC__' to 1 and handles function prototypes
-dnl correctly.
-dnl
-dnl If you use this macro, you should check after calling it
-dnl whether the C compiler has been set to accept ANSI C; if not,
-dnl the shell variable `ac_cv_prog_cc_stdc' is set to `no'. If
-dnl you wrote your source code in ANSI C, you can make an
-dnl un-ANSIfied copy of it by using the program `ansi2knr', which
-dnl comes with Ghostscript.

-dnl Arguments: LIBRARY = name of a Perl library to check for
-dnl
-dnl Use: Ensures that a Perl script can `use LIBRARY;'. If it can,
-dnl all's well and good; if it can't, `LIBRARY.pm' is added to
-dnl the variable `NEEDED_PERLLIBS' and a line which adds
-dnl `pkgdatadir' to Perl's `@INC' array is placed in the
-dnl variable `INC_PERLLIBS'; `AC_SUBST' is called for both of
-dnl these variables. It's expected that `NEEDED_PERLLIBS' will
-dnl be used in the `Makefile.in' to decide which versions from
-dnl the distribution need installing.
-dnl
-dnl This macro isn't terribly useful in the general case. It
-dnl Also implicitly assumes that `$PERL' is Perl 5 or later.
