- # 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.
