11# Contact dfavor@corridor.com for any of the following:
12#
13# - AIX 43x and above support
14# - gcc + threads support
15# - socks support
16#
17# Apr 99 changes:
18#
19# - use nm in AIX 43x and above
20# - gcc + threads now builds
29209bc5 21# [(added support for socks) Jul 99 SOCKS support rewritten]
bbc711f9 22#
23# Notes:
24#
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.
30#
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.
33#
34# better yet, a solid fix for this situation should be developed.
