+# 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.
