+# 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, when Dccflags=-DSOCKS specified
+#
+# 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.
