8 # Contact dfavor@corridor.com for any of the following:
10 # - AIX 43x and above support
11 # - gcc + threads support
16 # - shared libperl support is tricky. if ever libperl.a ends up
17 # in /usr/local/lib/* it can override any subsequent builds of
18 # that same perl release. to make sure you know where the shared
19 # libperl.a is coming from do a 'dump -Hv perl' and check all the
20 # library search paths in the loader header.
22 # it would be nice to warn the user if a libperl.a exists that is
23 # going to override the current build, but that would be complex.
25 # better yet, a solid fix for this situation should be developed.
28 # Configure finds setrgid and setruid, but they're useless. The man
30 # setrgid: The EPERM error code is always returned.
31 # setruid: The EPERM error code is always returned. Processes cannot
32 # reset only their real user IDs.
