#	This script munges the native include files provided with DYNIX/ptx
#	so as to remove things which are violations of the ANSI C standard.
#	This is done by first running fixinc.svr4 which does most of the
#	work.  A few includes have fixes made to them afterwards  by this
#	script.  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
#	DYNIX/ptx systems.  For other types of systems, you should use the
#	`fixincludes' script instead.
