8 # Andy Dougherty <doughera@lafcol.lafayette.edu>
11 # Contact dfavor@corridor.com for any of the following:
13 # - AIX 43x and above support
14 # - gcc + threads support
19 # - use nm in AIX 43x and above
20 # - gcc + threads now builds
21 # [(added support for socks) Jul 99 SOCKS support rewritten]
25 # - shared libperl support is tricky. if ever libperl.a ends up
26 # in /usr/local/lib/* it can override any subsequent builds of
27 # that same perl release. to make sure you know where the shared
28 # libperl.a is coming from do a 'dump -Hv perl' and check all the
29 # library search paths in the loader header.
31 # it would be nice to warn the user if a libperl.a exists that is
32 # going to override the current build, but that would be complex.
34 # better yet, a solid fix for this situation should be developed.
37 # Configure finds setrgid and setruid, but they're useless. The man
39 # setrgid: The EPERM error code is always returned.

41 # reset only their real user IDs.
