HRESULT_FROM_WIN32

[Nuklon]

Not entirely sure if it should be posted here or in CsWin32, but this macro would be useful to add (perhaps in HRESULT).

Your instincts are correct, this is a projection-specific request. (For example, here's what Rust does.)

Perhaps @AArnott can transfer this issue to avoid having to create another?

CsWin32 can already generate HRESULT_FROM_WIN32. You just have to ask for it in your NativeMethods.txt file.

Hmm, it didn't get generated for me last time, but it does now, thanks :)
