Well, evidently you have a completely different understanding of what 
the "important discussion" here is. I've simply been trying to respond 
to your emails in a manner I thought appropriate: I didn't think you 
were sending mails with the expectation that it is apparently 
unacceptable for me to respond to them, especially when they contain 
multiple explicit direct questions.

I've now reverted to a much older version of GCC which will hopefully waste much fewer of my old computer's CPU cycles, while also (provably) not constantly breaking my system with all the added warnings and errors every release.

I did not think Poe's law would become applicable to so many discussions 
on this mailing list, but here I am... I guess that leaves me with only 
one question: are you actually serious in your claim that this "much 
older version of GCC" will produce faster code than a recent one ?
