I don't think so either, but when you ask the compiler to call printf(),
and it calls puts() because it `knows' it is better, what else are you
left with?

I am fine with disabling the optimization, but as I said, it will make
our compiler different. I would rather convince the gcc team to consider
turning the bogus behavior off permanently.
