[boost] [math][bcp] rational.hpp doesn't get processed well by bcp

Hello, boost/math/tools/rational.hpp (in trunk, at least) includes files by constructing a macro, e.g.: # define BOOST_HEADER() <BOOST_JOIN(boost/math/tools/detail/polynomial_horner1_, BOOST_MATH_MAX_POLY_ORDER).hpp> # include BOOST_HEADER() bpc doesn't seem to pick up dependencies that are included in this fashion - is it possible to include something into rational.hpp to serve as a hint to bcp on what all files might be included? Thanks, Stjepan
