+# 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.
