Is sh3 being built by Debian at all? :-?

I can apply the patch as-is, but that will affect the whole codebase.
I wonder if you prefer / have tried to disable -O2 only on the file(s)
that cause problems? This can be useful:

Your patch will go in the next release, so if you change your mind and
instead of using -O1 globallly you prefer to try with #pragma optimize
tell me!
