That's the kind of answer i'd get from gcc-help and at that point i'd
be none wiser because i already know that. I also know that up to
gcc-4.3-20070608 it was provably giving correct results faster than
any other variants. Being no language lawyer, that's the only metric i
consider.
It's no portability issue either because every compiler asks for a
specific work around; which is quite sad considering how mundane that
code is.
