+# 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.
