I fail to see any regression from 3.3.1 to current 3.3 branch (20031107). It looks like the loop 
optimizer is taking the biggest chunk of time, but still, under 1/3 of total compile time. Using 
flags -O3 -funroll-all-loops, the whole things takes around 120 seconds, 500 megs. With only -
O3, it gets aways with 70 seconds and 400 megs. On mainline it's even worse: 205 seconds for 
only -O3. I'll see if I can shrink the code a bit for a better testcase...
