This allows to use any compatible types with INTERLOCKED_* macros, not just the ones strictly matching the particular implementation of the intrinsics. In particular, this fixes compilation for Cygwin64, which is an LP64 target, meaning that long is 64-bit and _Interlocked* intrinsics use a different integer type for its 32-bit integer arguments. Additionally, enable use of intrin.h on Cygwin (32-bit). The test has been updated to explicitly use 32-bit integer arguments.
