10 # Contact dfavor@corridor.com for any of the following:
12 # - AIX 43x and above support
13 # - gcc + threads support
18 # - use nm in AIX 43x and above
19 # - gcc + threads now builds
20 # - added support for socks, when Dccflags=-DSOCKS specified
24 # - shared libperl support is tricky. if ever libperl.a ends up
25 # in /usr/local/lib/* it can override any subsequent builds of
26 # that same perl release. to make sure you know where the shared
27 # libperl.a is coming from do a 'dump -Hv perl' and check all the
28 # library search paths in the loader header.
30 # it would be nice to warn the user if a libperl.a exists that is
31 # going to override the current build, but that would be complex.
33 # better yet, a solid fix for this situation should be developed.
36 # Configure finds setrgid and setruid, but they're useless. The man
38 # setrgid: The EPERM error code is always returned.
39 # setruid: The EPERM error code is always returned. Processes cannot
40 # reset only their real user IDs.
48 # Intuiting the existence of system calls under AIX is difficult,
49 # at best; the safest technique is to find them empirically.
51 # AIX 4.3.* and above default to using nm for symbol extraction

66 # Make setsockopt work correctly. See man page.
