+dnl Synopsis : AC_CC_WARNINGS([ANSI])
+dnl
+dnl Version : 1.1 (2000/12/31)
+dnl
+dnl Author : Ville Laurikari <vl@iki.fi>
+dnl
+dnl Description :
+dnl
+dnl Enables a reasonable set of warnings for the C compiler.
+dnl Optionally, if the first argument is nonempty, turns on
+dnl flags which enforce and/or enable proper ANSI C if such
+dnl flags are known to the compiler used.
+dnl
+dnl Currently this macro knows about GCC, Solaris C compiler,
+dnl Digital Unix C compiler, C for AIX Compiler, HP-UX C
+dnl compiler, and IRIX C compiler.
