43dnl Synopsis: AC_PROG_CC_STDC
44dnl
45dnl Arguments: ---
46dnl
47dnl Use: If the C compiler in not in ANSI C mode by default, try to
48dnl add an option to output variable `CC' to make it so. This
49dnl macro tries various options that select ANSI C on some system
50dnl or another. It considers the compiler to be in ANSI C mode
51dnl if it defines `__STDC__' to 1 and handles function prototypes
52dnl correctly.
53dnl
54dnl If you use this macro, you should check after calling it
55dnl whether the C compiler has been set to accept ANSI C; if not,
56dnl the shell variable `ac_cv_prog_cc_stdc' is set to `no'. If
57dnl you wrote your source code in ANSI C, you can make an
58dnl un-ANSIfied copy of it by using the program `ansi2knr', which
59dnl comes with Ghostscript.

1071dnl IF-FOUND = what to do when the function is found
1072dnl IF-NOT-FOUND = what to do when the function isn't found
1073dnl
1074dnl Use: Searches for a library which defines FUNC. It first tries
1075dnl without any libraries; then it tries each library specified
1076dnl in LIBS in turn. If it finds a match, it adds the
1077dnl appropriate library to `LIBS'.
1078dnl
1079dnl This is particularly handy under DIREIX: if you link with
1080dnl `-lnsl' then you get non-NIS-aware versions of getpwnam and
1081dnl so on, which is clearly a Bad Thing.
