I'll do once I figure out what's going on...  Eric's suggestion moved me
past the immediate problem, but now I am having another one, related to
sizeof(...) not being recognized as a constant expression...

A good news is that I probably know how to fix it by simplifying (removing
some optimization), so that VC8 is able to handle this -- it works with my
preliminary tests.  The price will be decreased performance of
BOOST_TYPEOF_TPL (but not BOOST_TYPEOF) in VC8 only, for simple types, but
your example should be fixed once I do this.

Until I find a better solution it probably makes sense to upload the patched
version, so that we could move on with the review.  I'll do it some time
tomorrow if I don't find anything better until then.
