These intrinsics should (must?) have '()' around them. Hence:

Thanks, revised patch attached.
I'm not at Win64 (x86_amd64) to check the test-results.
Can you please test it sometime soon?
And maybe the 'ifndef _M_IX86' should be rewritten as:
'if defined(_M_X64) || defined(_M_AMD64)'.
That would complicate the code slightly, with no advantage that I can see.
