Here is what the compiler says:

C:\BoostHead\libs\serialization\build\../src/xml_grammar.cpp:
Support for Borland compilers older than BCB2006 is deprecated in Boost 1.34
Error E2238 C:\BoostHead\boost/type_traits/floating_point_promotion.hpp 32:

I suspect that const and volitile versions have to be conditioned on 
BOOST_NO_CV_SPECIALIZATIONSas described in 
http://www.boost.org/libs/config/config.htm#defects
