--- Comment #1 from Rafał Mużyło galtgendo@o2.pl --- Correct me if I'm wrong, but the way I understand it, that particular winhttp.dll is an injection proxy.
If so, your argument is at least slightly flawed.
I could bring up an old HD patch for Fallout (or was it Fallout 2 ?), that used ddraw.dll as such proxy. That is to say, your argument, if correct, would fit pretty much any Windows system dll (well, any that Windows allows to be proxied).
I mean, even apitrace needs to live with explicit DLLOVERRIDES when its Windows version is run with wine.
