AIX 3 hints split off from default hints in preparation
of a hint file cleanup. aix_4.sh will follow soon

+#    - 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.
