I'm changing the target milestone because the problem is a fundamental flaw in
the new heuristics of the tree inliner, which I think cannot be fixed on a
release branch. I'll try to come up with something sensible for the 3.4 release.

Meanwhile, a workaround is to compile with

   -O2 --param max-inline-insns-single=180

which will bring the compile time on par with GCC 3.2.3.
