| 26 | # This script munges the native include files provided with SCO |

| 27 | # 3.2v4 systems so as to provide a reasonable namespace when |
---|
| 28 | # compiling with gcc. The header files by default do not |
---|
| 29 | # provide many essential definitions and declarations if |
---|
| 30 | # __STDC__ is 1. This script modifies the header files to check |
---|
| 31 | # for __STRICT_ANSI__ being defined instead. Once munged, the |
---|
| 32 | # resulting new system include files are placed in a directory |

---|
| 34 | # directory. This script should work properly for most SCO |
