I copied the 32-bits Interlocked64 definition from my patch, changed 
LONG64 to long long, and WINAPI to __attribute__((__stdcall__)) and then 
tried a few calls against the inline and it works fine and compare the 
returned and expected result, which seem to work for the case where it 
should replace, and where it shouldn't replace. Tests also run against 
the kernel32 assembly version. versionInterlockedCompareExchange64 when 
available.

The 64-bits InterlockedCompareExchange64 assembly call is copied from 
InterlockedCompareExchangePointer

What are the remaining problems then?

Cheers,
Maarten.
