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