49dnl Synopsis: AC_PROG_CC_STDC
50dnl
51dnl Arguments: ---
52dnl
53dnl Use: If the C compiler in not in ANSI C mode by default, try to
54dnl add an option to output variable `CC' to make it so. This
55dnl macro tries various options that select ANSI C on some system
56dnl or another. It considers the compiler to be in ANSI C mode
57dnl if it defines `__STDC__' to 1 and handles function prototypes
58dnl correctly.
59dnl
60dnl If you use this macro, you should check after calling it
61dnl whether the C compiler has been set to accept ANSI C; if not,
62dnl the shell variable `ac_cv_prog_cc_stdc' is set to `no'. If
63dnl you wrote your source code in ANSI C, you can make an
64dnl un-ANSIfied copy of it by using the program `ansi2knr', which
65dnl comes with Ghostscript.
