In fact, I can't imagine why one would use
BOOST_TT_AUX_BOOL_TRAIT_DEF1 here; that's meant for public-interface
metafunctions of the type traits library.  It seems to have been used
without an understanding of its purpose.  I suggest a quick review of
all the type traits implementation macro usage in this file.

The enclosed seems to fix the problem.
