Too long to paste into forum, so I pasted the error log here instead:

Fixed - and FYI, I'd like to slap the LZMA programmer into the face with a wet fish for his ill-advised idea to include windows.h in every file that needs to do LZMA decompression.
ZDoom had to include this in a header that was used everywhere so I had to add some not quite nice workaround.

Haha, that sounds like really redundant programming. Thanks the fix!
