Jonathan, does your CW 8.3 problem has to do with premature
execution of the guard code? if so, then this is due not to your
code, but to a compiler bug about the lifetime of temporary
objects bound to references. See the following for a
description:

http://lists.boost.org/MailArchives/boost/msg65882.php

This problem happens only when the "ISO C++ Template Parser"
mode is on, so it can be avoided by explicitly setting
the mode off with pragmas. Go to boost/multi_index_container.hpp
and search for the two occurrences of parse_mfunc_templ in
lines 77 and 531.

Hope this helps,
