46dnl Synopsis: AC_PROG_CC_STDC
47dnl
48dnl Arguments: ---
49dnl
50dnl Use: If the C compiler in not in ANSI C mode by default, try to
51dnl add an option to output variable `CC' to make it so. This
52dnl macro tries various options that select ANSI C on some system
53dnl or another. It considers the compiler to be in ANSI C mode
54dnl if it defines `__STDC__' to 1 and handles function prototypes
55dnl correctly.
56dnl
57dnl If you use this macro, you should check after calling it
58dnl whether the C compiler has been set to accept ANSI C; if not,
59dnl the shell variable `ac_cv_prog_cc_stdc' is set to `no'. If
60dnl you wrote your source code in ANSI C, you can make an
61dnl un-ANSIfied copy of it by using the program `ansi2knr', which
62dnl comes with Ghostscript.
