#	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.
#
