| # AIX 3 and AIX 4 are split off to aix_3.sh and aix_4.sh |
| # early Feb 2004 by H.Merijn Brand |
| # please read comments in there for historic questions. |
| # many now stripped here |
| |
| # Contact dfavor@corridor.com for any of the following: |
| # |
| # - AIX 43x and above support |
| # - gcc + threads support |
| # - socks support |
| # |
| # Notes: |
| # |
| # - shared libperl support is tricky. if ever libperl.a ends up |
| # in /usr/local/lib/* it can override any subsequent builds of |
| # that same perl release. to make sure you know where the shared |
| # libperl.a is coming from do a 'dump -Hv perl' and check all the |
| # library search paths in the loader header. |
| # |
| # it would be nice to warn the user if a libperl.a exists that is |
| # going to override the current build, but that would be complex. |
| # |
| # better yet, a solid fix for this situation should be developed. |
| # |
| |
| # Configure finds setrgid and setruid, but they're useless. The man |
| # pages state: |
| # setrgid: The EPERM error code is always returned. |
| # setruid: The EPERM error code is always returned. Processes cannot |
| # reset only their real user IDs. |
