Finished merging the condexec bits to mainline. Whoo hoo.

Decided that my headache wasn't quite pounding at the proper weekend-bender level, so I dived face-first into the gcc build configury. There is much progress. Why, already I have replaced 380 lines of completely unreadable make+sh with 280 different lines of even less readable make+sh.

Tomorrow I'll try to bulk that back out to 500 or so with brand new shared library build cruft. Wouldn't want anyone to think I was going soft.
