boost/external: More fixes for clang-cl

* Avoid errors about (somewhat different, but apparently in a way that MSVC
  doesn't care) redeclarations of system header stuff (and working around that
  with BOOST_USE_WINDOWS_H would lead to other problems).

* Need the workaround for broken MSVC 2010 STL iterator taxonomy for clang-cl,
  too.
