4849,MinGW-64: detail/interlocked.hpp chooses wrong prototypes for InterlockedCompareExchange et al,Jim Bell <jim@…>,Anthony Williams,"I see pdimov's name on detail/interlocked.hpp, so I'm filing this here...

MinGW-64/Win7 fails to compile thread.cpp, so all dependent regressions fail.
{{{

                 from ..\libs\thread\src\win32\thread.cpp:17:

}}}

If I modify detail/interlocked.hpp to choose it as BOOST_USE_WINDOWS_H, thread.cpp builds and dependent tests pass. It seems BOOST_USE_WINDOWS_H is special-purpose, so I'm not sure if this is the final fix.
{{{
#if defined( BOOST_USE_WINDOWS_H ) || defined(_WIN64)
}}}

Presently it's choosing this section (line 107):
{{{
#elif defined( WIN32 ) || defined( _WIN32 ) || defined( __WIN32__ ) || defined( __CYGWIN__ )
}}}
