+MAC OSX NOTES
+-------------
+
+Mac OS X (Darwin) seems to have an IPv6 stack, but it does not
+completely implement the "New Sockets" API.
+
+<http://www.ipv6.org/impl/mac.html> says that Apple do not support
+IPv6 yet. If your build fails, try again with --disable-ipv6.
+
+There is an unresolved problem with the OSX implimentation
+of setgroups causing rsyncd to fail. The workaround is to
+#undef HAVE_SETGROUPS in config.h
+
+IBM AIX NOTES
+-------------
+
+IBM AIX has a largefile problem with mkstemp. See IBM PR-51921.
+The workaround is to append the below to config.h
+ #ifdef _LARGE_FILES
+ #undef HAVE_SECURE_MKSTEMP
+ #endif
