You're going to get a nice surprise soon, then, because the tree-ssa optimizers have finally reached the stage where some of the horrible slow old RTL optimizers are being removed or drastically simplified, as the much faster tree-ssa optimizers can supplant them entirely, and take much less time to do much more work...
Note, `soon' here means `GCC 4.3'; the mem-ssa work reduces the size of the intermediate representation so much that the improvement to cache utilization alone causes significant compile-time speedups.

GCC 4.2 is indeed yet another slower-at-compiling release. (mem-ssa is far too large to backport...)
