OK, I got access to some older machines, and it appears that Core is the only
architecture that likes gcc 4's code. More precisely, I have confirmed that
the following architectures run significantly slower using gcc4 than gcc 3:
Pentium-D, P4e, Pentium III, PentiumPRO, Athlon-64 X2, Opteron.
Any help appreciated,
Clint
