78 | dnl |
79 | dnl Arguments: --- |
80 | dnl |
81 | dnl Use: If the C compiler in not in ANSI C mode by default, try to |
82 | dnl add an option to output variable `CC' to make it so. This |
83 | dnl macro tries various options that select ANSI C on some system |
84 | dnl or another. It considers the compiler to be in ANSI C mode |
85 | dnl if it defines `__STDC__' to 1 and handles function prototypes |
86 | dnl correctly. |
87 | dnl |
88 | dnl If you use this macro, you should check after calling it |
89 | dnl whether the C compiler has been set to accept ANSI C; if not, |
90 | dnl the shell variable `ac_cv_prog_cc_stdc' is set to `no'. If |
91 | dnl you wrote your source code in ANSI C, you can make an |
92 | dnl un-ANSIfied copy of it by using the program `ansi2knr', which |
93 | dnl comes with Ghostscript. |
