Thanks for the research. I sent a question to gcc-help. It's a high traffic list so I try to keep unsubscribed, but in this case I decided to subscribe again. I used your log file, I hope you don't mind. I'm kinda reluctant to dive into the gcc build scripts, because of the multi-level builds, where the top-level Makefile calls multiple configure scripts with different options to build different targets. I mean, you can debug it if you really want, but it takes a long time and you have to keep a lot of state in your head. I'll wait for a response from gcc-help, guys over there have always been helpful (and also think I'm crazy, but that's another issue).
