I did suggest that in a previous message, but Jens was against it,
personally I don't mind either way.

What else should we do? gcc on Win32 has a "short" wchar_t, where as it's
int sized on all other gcc platforms as far as I know.

>BOOST_STATIC_CONSTANT?

Sure, I just ran out of time, although as this is basically a gcc only
workaround does it matter that much?
