-# If the C compiler in not in ANSI C mode by default, try to add an option
-# to output variable @code{CC} to make it so.  This macro tries various
-# options that select ANSI C on some system or another.  It considers the
-# compiler to be in ANSI C mode if it defines @code{__STDC__} to 1 and
-# handles function prototypes correctly.
-# 
-# If you use this macro, you should check after calling it whether the C
-# compiler has been set to accept ANSI C; if not, the shell variable
-# @code{fp_cv_prog_cc_stdc} is set to @samp{no}.  If you wrote your source
-# code in ANSI C, you can make an un-ANSIfied copy of it by using the
-# program @code{ansi2knr}, which comes with Ghostscript.
