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