ptw32_MCS_lock.c should include windows.h.  

Unfortunately, the documentation doesn't mention which library provides
InterlockedExchangePointer.  It is possible, though, that the function's
true name is slightly different (the result of some preprocessor magic in
windows.h) and is provided by a library you're already linking to.  By
including the header file, the compiler will import the correct name,
eliminating both the compile-time warning and the linker error.
