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