Good.

It shouldn't. The change I forwarded to you should not effect ppc-linux
at all.

Yes. It had a real bug.

The way the ppc handles this is a little odd -- basically I don't think you
can depend on the info in the .s file to correctly tell you the right thing
for -mmultiple.

I rewrote this fix to be more correct. You shouldn't need Geoff's fix
for this problem anymore. My version has been in egcs snapshots for
several weeks.
