Sorry for being soooooooo late to reply. Just got back from a month and 
a half vacation...

It seems to me that the exception approach fits best to this case. I 
also like Daryle's idea of #ifdef-ing out the check when CHAR_BITS == 8, 
because the vast majority of Boost users do work in such environments, 
and would benefit from it.
