[boost] BUG: mpl and iso646.h in vc7

Boosters, Microsoft's macro hacks in the iso646.h header unfortunately kills the current MPL implementation. The headers or.hpp, and.hpp are substituted as ||.hpp, &&.hpp! Since the iso646.h header is typically force included at the project level, header re-arranging is not a practical solution. Any possibility of getting these headers renamed? Ian
