Startup times was optimized a bit in 4.3.

hashes.c, 100 compilations:
              GCC-3.3 GCC-3.4   mainline mainline&profiledbootstrap
-O0             3.2s    3.8s      3.6s        3.3s 
-O1             5s      5.6s      8.1s        7.4s  
-O2             7.7s    7.6s      12.4s       11.1s

So at least for -O0 we are back to original speed.
