Confirmed on x86. Text sizes for various versions:
4.0.0: 22324 (20040914)
4.0.0: 20130 (20040901)
3.4.2: 18064
3.3.4: 17952
3.2.2: 18413
3.0.4: 19681
2.95: 19490
The increment in the last two weeks is caused by ivopts, and in fact can be
reverted with -fno-ivopts. Zdenek, maybe ivopts must be tuned/disabled
specially for -Os?
This leaves use with 2k of code increase though, which should still be
investigated.
