Why is the ReactOS version of wininet out of sync with Wine?
As far as I know, it was imported once, a long time ago, and was way out of sync when the regular sync'ing of Wine stuff began. If I remember correctly, the problem at that moment was that wininet used Linux socket I/O instead of going through WinSock. I also have faint recollections of Alexandre insisting that it should remain that way and any differences between Wine and ReactOS should be handled by some creative use of the preprocessor. I don't know if all of this is still true (or indeed, I'm not 100% sure it was ever true...), I'll look into re-importing wininet.
