---|
| 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. |
