The point is that I'm not using such `non-standard' flags.  -O3
enables some optimizations that are not enabled with -O2, and some of
these optimizations must be broken, because it causes stage1 to build
a stage2 compile that doesn't work.

It's a pity that I don't have time to learn enough about the internals
of gcc to track this bug :-(
