[boost] floating_point_promotion question

including the header file floating_point_promotion.hpp results in a compile error with the borland compilers. Is there any chance this could be enhanced to avoid this? This became apparent when building serialization library with borland compilers. This occurs because, the header is included via a the "convenience" header type_traits.hpp. Which in turn is used by spirit Note that this is an example where the usage of a "convenience" header turns out to be "inconvenient". In this case it makes the serialization libary and spirit dependent not only on the code existent when these libraries were written, but on future code as well. Robert Ramey
