Well, I downloaded the source code AGAIN for 0106 and tried to recompile. Errors, but I started messing with the checkboxes. I assumed because I had a 64bit Quad core, i should check those boxes, but nope. Leaving everything blank EXCEPT "Clean Compile" and "Disable Warnings as Error" allowed me to compile 0106.

I started adding diffs (0106-0106u10.diff to be exact), and that's where I'm running into problems. 1st one said something along the lines of:
src/usrintrf.c:420: error: unterminated #ifndef
So I edited that file, found where the ifndef was opened and added the close tag after that section, which happened to be segmented by comments.
Ran again and now I'm getting:
Compiling src/timer.c...
Compiling src/ui_text.c...
Compiling src/unzip.c...
Compiling src/usrintrf.c...

Finished!
0 Hours 0 Minutes and 35 Seconds Elapsed.So I do have a working 0106, but I'll have to decide how much time I want to spend on these diffs. Value added vs. time.
Thanks for the input guys. Especially Headkaze. If I had to commandline this whole thing every time I'd have gone postal.
