Heads-up, anyone who keeps their Mac software up-to-date

Recipe for repair:
1. Have a copy of XCode 4.6.3 on backup (I think it might fit on a DVD, just to be extra careful).
2. Installing the tools seems to burn a particular path into their tiny pea brain, so in the end you will need to call XCode 4.6.3 "XCode.app", if that is its old name, because I cannot figure out how to convince XCode that it should re-install tools.
This may require moving the upgraded XCode.app to XCode5.0.app.
3. "sudo xcode-select --switch /Applications/XCode.app" did NOT put the tools (/usr/bin/gcc and /usr/bin/g++) back the way they should be. Instead, it is necessary to manually remove them and recreate the symlinks, like so:
mv gcc xxx
mv g++ xxx
ln -s ../llvm-gcc-4.2/bin/llvm-gcc-4.2 gcc
ln -s ../llvm-gcc-4.2/bin/llvm-g++-4.2 g++
If there's no /usr/llvm-gcc-4.2, that's a problem I didn't have.
This succeeded -- it configured properly (fastdebug), built, and the resulting java (built minutes ago) successfully ran.
