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.
