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