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 |

33 | # `fixincludes' script instead. |
