Why is neccessary to include the windows headers at all? Intrin.h seems
to be enough: it declares _InterlockedCompareExchange and some other
useful intrinics, and it does not use the winapi-related stuff.

Checked on MSVC 2008 and 2010. I remember that I had some problems with
interlocked functions and intrinics several years ago (with MSVC6,
probably), but now I cannot reproduce them.
