Please feel free to fix any of them that you feel comfortable about. I wonder why gcc doesn't warn about those. It just doesn't implement truncation warnings between variables of differently-sized integer types. This (typically) isn't undefined behaviour: the C standard mandates very well what should happen for these truncations. Warning about any and all truncations would lead to incredible noise. /Wp64 *only* works because they restrict themselves to int64-int32 warnings (essentially).

Currently I'm not, because the VSExtCompiler Plugin cannot determine the SDK path from the registry. This is vsextcomp 0.6. I have installed the 2003 Server SP1 SDK.

Right; I was planning something similar (although I would probably hard-code the 2003 SP1 registry key - it is not at all certain that future SDK releases will use the same registry scheme, and Microsoft has tricked users often enough in thinking they understood the scheme, just to change it with the next release entirely).
