HRESULTs and headers

[Mike Hearn]

Good morning everybody!

I was wondering if anybody knew where I could find a definitive list of
HRESULT values, as the one I want to know, 0x80770001, is not in the
Wine headers, nor on Google.

Is there somewhere that I can get the official set of headers for free?
I don't want to buy Visual Studio just to get them (the mingw headers
are partially taken from Wine I think).
