wininet has an INTERNET_SetLastError() which calls SetLastError() and does some extra tricks (see dlls/wininet/internet.c:3041).
The problem is that while most functions use it, some call SetLastError() directly, seemingly without pattern or reason. Some functions even call one or the other depending on the error condition!
So I propose the following patch to systematically call INTERNET_SetLastError(). However I have left the functions in cookie.c and urlcache.c unchanged as none of them calls INTERNET_SetLastError(). I have no idea if that's right or not.
If I get no objection I will submit this patch to wine-patches in a few days. Otherwise I would be happy if someone could straighten this out the right way, and add explanatory comments in the places where SetLastError() should be called instead of INTERNET_SetLastError().
