Details
When doing a no-op Fennec build on my mac, I would see jsapi.cpp along with a bunch of other js/src/ files getting rebuilt. Upon investigating I found that this was a result of MethodGuard.h and MethodGuard-inl.h being removed from js/src/vm/ almost a month ago.
After MethodGuard.* was removed, some of the *.o.pp files in <objdir>/js/src/.deps/ still referenced those .h files as dependencies. js/src/build/unix/mddepend.pl looks for those non-existent .h files, doesn't find them, and emits rules of the form "jsapi.cpp: FORCE", forcing a rebuild of jsapi.cpp.
Blowing away my <objdir>/js/src/.deps folder fixed this particular issue, but it seems like a deficiency in the build system that should be fixed.

Wow, that's horrible.

Same thing with the removal of netwerk/base/src/PrivateBrowsingConsumer.h causing rebuilds of a variety of code in netwerk/protocol/**, etc.
Setting DEBUG to 1 in mddepend.pl and grepping build output for "Couldn't stat" seems like a good way of catching these, if anybody else is seeing the same problem.
Uh, why aren't the .pp files getting regenerated?

I don't know. I already blew away my objdir and rebuilt so I can't easily check that anymore either.
