well, format makes that decision based on 
BOOST_NO_STD_WSTRING and BOOST_NO_STD_WSTREAMBUF : 

#if !defined(BOOST_NO_STD_WSTRING) && !defined(BOOST_NO_STD_WSTREAMBUF) 
typedef basic_format<wchar_t >  wformat; 
#endif 

Are you saying those macros are defined, in boost/config, according to
BOOST_NO_USING_TEMPLATE ?

it's quite strange that this line works with basic char, and not
wchar_t.. 
maybe wchar_t really is a strange faked type on your platform, that
causes all kinds of trouble ?

well, I had just made a few minor modifications into CVS to make format
more robust versus locale being here or not, so it certainly might have
solved some of the issues you faced.
