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

1391 | dnl |
1392 | dnl --enable-tracing turns off the NTRACE variable |
1393 | dnl --enable-track turns on malloc tracking |
1394 | dnl --enable-blame-PROGRAM tracks malloc contexts in PROGRAM |
