Again, do you have _any_ evidence of improved code generation with that
patch?  Because if you do, I would really like to see it, so I could file
bugs against gcc optimizer.

Your impression of what _Bool is and what semantics does it have appears
to be rather different from that described in C99, but that's a secondary
issue - first and foremost, on which .config and with which gcc version
do you see improvements from that change?
