Exctracted from http://www.suse.de/~gcctest/c++bench/polyhedron/polyhedron-summary.txt:

date   compile execute

070608  106.29  628.74
070615  117.43  629.73
070620  105.95  616.99

So these tests show a ~10% increase of the compilation time
from 070612 to 070618.  I have forgotten to mention that my timings
were done on a 1.8Ghz G5 with 512k of cache. My observation is that
when something goes wrong on the x86 family it is several time worse
on the PPC. This is particularly important when cache misses are involved.

So I'll wait for the next snapshot and report what I see.

Cheers

Dominique
