Thank you, Egor! I didn't realize that it was so easy to fix these.

I'm in favor of it, in general, but I think there's one bogus warning in
fork.cc currently -- at least under gcc 2.95.3. It is the "setjmp/longjmp
may clobber local variable" warning (this is not the exact text but it is
something like that).
