12 # Contact dfavor@corridor.com for any of the following:
14 # - AIX 43x and above support
15 # - gcc + threads support
20 # - use nm in AIX 43x and above
21 # - gcc + threads now builds
22 # [(added support for socks) Jul 99 SOCKS support rewritten]
26 # - shared libperl support is tricky. if ever libperl.a ends up
27 # in /usr/local/lib/* it can override any subsequent builds of
28 # that same perl release. to make sure you know where the shared
29 # libperl.a is coming from do a 'dump -Hv perl' and check all the
30 # library search paths in the loader header.
32 # it would be nice to warn the user if a libperl.a exists that is
33 # going to override the current build, but that would be complex.
35 # better yet, a solid fix for this situation should be developed.
38 # Configure finds setrgid and setruid, but they're useless. The man
40 # setrgid: The EPERM error code is always returned.
41 # setruid: The EPERM error code is always returned. Processes cannot
42 # reset only their real user IDs.
