Compared to gcc 2.95 with -march=i686 (or i586, as the case may be)? That
sounds a lot higher from what I've heard, even from those who would boost
it (the Intel engineers, for instance.)
Be that as it may, you didn't answer the rest of my claims, or the arguments
that's too unstable to be used. Nobody's going to complain if someone puts
together a pgcc deb, but a pgcc/i686 distribution is going to take up manpower
and archive space that the developers* don't want to support.
