25: # This script munges the native include files provided with DYNIX/ptx
26: # so as to remove things which are violations of the ANSI C standard.
27: # This is done by first running fixinc.svr4 which does most of the
28: # work. A few includes have fixes made to them afterwards by this
29: # script. Once munged, the resulting new system include files are
30: # placed in a directory that GNU C will search *before* searching the
31: # /usr/include directory. This script should work properly for most
32: # DYNIX/ptx systems. For other types of systems, you should use the
33: # `fixincludes' script instead.
