5# AIX 4.1 hints thanks to Christopher Chan-Nui <channui@austin.ibm.com>.
6# AIX 4.1 pthreading by Christopher Chan-Nui <channui@austin.ibm.com> and
7# Jarkko Hietaniemi <jhi@iki.fi>.
8# AIX 4.3.x LP64 build by Steven Hirsch <hirschs@btv.ibm.com>
9# Merged on Mon Feb 6 10:22:35 EST 1995 by
10# Andy Dougherty <doughera@lafayette.edu>

12# Contact dfavor@corridor.com for any of the following:
13#
14# - AIX 43x and above support
15# - gcc + threads support
16# - socks support
17#
18# Apr 99 changes:
19#
20# - use nm in AIX 43x and above
21# - gcc + threads now builds
22# [(added support for socks) Jul 99 SOCKS support rewritten]
23#
24# Notes:
25#
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.
31#
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.
34#
35# better yet, a solid fix for this situation should be developed.
36#
37
38# Configure finds setrgid and setruid, but they're useless. The man
39# pages state:
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.
