+#	This script munges the native include files provided with SCO
+#	3.2v4 systems so as to provide a reasonable namespace when
+#	compiling with gcc.  The header files by default do not
+#	provide many essential definitions and declarations if
+#	__STDC__ is 1.  This script modifies the header files to check
+#	for __STRICT_ANSI__ being defined instead.  Once munged, the
+#	resulting new system include files are placed in a directory
+#	that GNU C will search *before* searching the /usr/include
+#	directory.  This script should work properly for most SCO
+#	3.2v4 systems.  For other types of systems, you should use the
+#	`fixincludes' or the `fixinc.svr4' script instead.
+#
+#	See README-fixinc for more information.
