+	WARNING:
+	------- 
+	Some versions of gcc have a bug that generates incorrect 
+	code if strength reducing is enabled. 
+	If you modify the compiler flags, always use the -fno-strength-reduce 
+	option with gcc, unless you are sure that your compiler does not
+	suffer from the problem (see README.gcc_bug).
+	Also, some gcc versions generate incorrect code unless the
+	-fno-omit-frame-pointer option is used. 
+	The -fno-strength-reduce and the -fno-omit-frame-pointer options are 
+	enabled by default by the 'configure' script.
