# hints/aix.sh
# AIX 3.x.x hints thanks to Wayne Scott <wscott@ichips.intel.com>
# AIX 4.1 hints thanks to Christopher Chan-Nui <channui@austin.ibm.com>.
# AIX 4.1 pthreading by Christopher Chan-Nui <channui@austin.ibm.com> and
# Jarkko Hietaniemi <jhi@iki.fi>.
# Merged on Mon Feb 6 10:22:35 EST 1995 by
# Andy Dougherty <doughera@lafcol.lafayette.edu>
#
# Contact dfavor@corridor.com for any of the following:
#
# - AIX 43x and above support
# - gcc + threads support
# - socks support
#
# Apr 99 changes:
#
# - use nm in AIX 43x and above
# - gcc + threads now builds
# [(added support for socks) Jul 99 SOCKS support rewritten]
#
# Notes:
#
# - shared libperl support is tricky. if ever libperl.a ends up
# in /usr/local/lib/* it can override any subsequent builds of
# that same perl release. to make sure you know where the shared
# libperl.a is coming from do a 'dump -Hv perl' and check all the
# library search paths in the loader header.
#
# it would be nice to warn the user if a libperl.a exists that is
# going to override the current build, but that would be complex.
#
# better yet, a solid fix for this situation should be developed.
#
# Configure finds setrgid and setruid, but they're useless. The man
# pages state:
# setrgid: The EPERM error code is always returned.
# setruid: The EPERM error code is always returned. Processes cannot
# reset only their real user IDs.
