If so, we should work out a proper solution instead of the inlineasm hack. The integer runtime functions (_allmul, _alldiv, etc. for 64-bit integer arithmetic) all appear to be straight-up stdcall. _ftol2 is the only weird one. (There is an _ftol routine with the same calling convention as _ftol2, but AFAIK it's only for backward compatibility with older MSVC runtimes.) I'm far from an MSVC expert, tho...
