r68300 removed boost/type_traits/broken_compiler_spec.hpp and boost/type_traits/transform_traits_spec.hpp.

Removing the first broke regression tests for iterator, python, and serialization.

Removing the second doesn't appear to have done any harm.

John Maddock did the r68300 commit. I'm assuming it was in response to Steve Kelly's r86250, "Remove use of obsolete BOOST_TT_BROKEN_COMPILER_SPEC", so the fix may be to remove the #includes that are causing all the errors rather than restoring the file.

Apologies, my bad, I'd checked the headers for that file, but not the tests :-( I've deleted all references to the file - there was nothing in it after Steve Kelly's changes so it makes sense to remove it. Thanks for the heads up, John.
