  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.
