[boost] TT_AUX_IS_CONVERTIBLE_FROM_FLOAT_CV_SPEC in type_traits/is_convertable.hpp

These three lines near the end of boost/type_traits/is_convertable.hpp:

TT_AUX_IS_CONVERTIBLE_FROM_FLOAT_CV_SPEC(float)
TT_AUX_IS_CONVERTIBLE_FROM_FLOAT_CV_SPEC(double)
TT_AUX_IS_CONVERTIBLE_FROM_FLOAT_CV_SPEC(long double)

don't compile on GCC 3.4.1 when -pedantic is specified.

This is actually sort of strange, because it compiles without warnings
when -std=c++98 -Wall -W are specified, and -pedantic itself is not
supposed to generate errors, only warnings.  So, there is probably at
least a GCC bug here.  Does anyone have any idea what this is about?
