I can speak in favor of any serious effort to try to verify that
our binaries match our souce code.

I did not understand, until now, that this was meant as a way to verify GCC.
I thought you meant we should stop using our existing tools and program
in this language instead.  I was not interested in that.

However, as a scheme to verify our tools and keep using them,
it might make sense.  I can't judge how effective this sort of proof
might be, but I won't reject the idea.
