# 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>.
|
|
# AIX 4.3.x LP64 build by Steven Hirsch <hirschs@btv.ibm.com>
|
|
# Merged on Mon Feb 6 10:22:35 EST 1995 by
|
|
# Andy Dougherty <doughera@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.
