TypeIndex has been tested on MSVC2010, GCC-4.5, Clang-2.9. There is
currently no list of supported compilers. If TypeIndex would be
accepted into boost, support for all compilers running regression
tests will be added.

You can also define BOOST_TYPE_INDEX_CTTI_BEGIN_SKIP and
BOOST_TYPE_INDEX_CTTI_END_SKIP for your compiler. Consider the
following example:
BOOST_CURRENT_FUNCTION for boost::detail::ctti<int>:: returns "const
char *__cdecl boost::detail::ctti<int>::n(void)". Then you shall set
BOOST_TYPE_INDEX_CTTI_BEGIN_SKIP to sizeof("const char *__cdecl
boost::detail::ctti<") - 1 and BOOST_TYPE_INDEX_CTTI_END_SKIP to
sizeof(">::n(void)") - 1

I`ll add documentation for those macroses and fix TypeIndex on clang-3.1 ASAP.

Thanks for a good advise!
