Here is my timings for 3.3.2 vs the mainline on powerpc-darwin (yesterdays before a patch which 
should speed it up a little  more):
[zhivago:~/src/localgccPRs] pinskia% time ~/gcc-3.3//bin/gcc pr16613.ii -S -D__DEBUG__ -O2
5.600u 0.340s 0:06.99 84.9%     0+0k 0+3io 0pf+0w
[zhivago:~/src/localgccPRs] pinskia% time ~/local3/bin/gcc pr16613.ii -S -D__DEBUG__ -O2
6.190u 0.590s 0:07.69 88.1%     0+0k 0+0io 0pf+0w

Plus this is a mainline preprocessed source so it looks like the mainline is slightly slower than 3.3.2 
(about 10%).

For -O0:
[zhivago:~/src/localgccPRs] pinskia% time ~/gcc-3.3//bin/gcc pr16613.ii -S -D__DEBUG__
2.980u 0.260s 0:04.70 68.9%     0+0k 0+0io 0pf+0w
[zhivago:~/src/localgccPRs] pinskia% time ~/local3/bin/gcc pr16613.ii -S -D__DEBUG__
1.600u 0.270s 0:02.29 81.6%     0+0k 0+0io 0pf+0w

So we are much faster for -O0.
