I decided to defragment my P166, but I think I made it worse (6 mins!), so I'm using a tweaked defragment setting (full w/ file reorder). That's going to take a while, though, but I need to test again as soon as it's finished.

Okay, I think I solved part of the issue, and it's not that big a shock (but still surprising): UPX. I tested it on my aunts' P4, and that's what clued me off. Unpack the .EXEs and try again: upx -d /djgpp/.../*.exe. After this, my AMD64x2 (using GCC 4.2.2) only took 49 secs to compile TDE 5.1v. See, they only started packing everything fairly recently (after the UPX 1.25 djgpp/coff bug was fixed).

Just FYI in case anyone needs to compile anything huge with DJGPP or whatever: unpack the .EXEs first, it's faster that way.
