Unfortunately, to get rid of this one, you will need to modify your copy of
"boost/mpl/aux_/config/preprocessor.hpp" header:

#if defined(__MWERKS__) && (__MWERKS__ <= 0x3003 ||
!defined(BOOST_STRICT_CONFIG)) \

line needs to become

#if defined(__MWERKS__) && __MWERKS__ <= 0x3003 \

I just fixed it in the CVS, so at least the change will go into the next
release.

HTH,
Aleksey
