The are not regressions from 3.0, in that 3.0 had these broken
already.  On the other hand, I think I'm missing something.  3.0.1
will only fix what? further regressions in the 3.0.1 snapshots?
Wasn't it supposed to address the 2.95.3->3.0 regressions?  (that's
what you get for not following that part of the mailing list).

In any event, I'm not able to track down the breakpoint.  There is a
fairly detailed analysis in some of the gnats reports I mentioned, and
there was someone else who posted something about the groff bug:

	   George Garvey <tmwg-gcc at inxservices dot com>

Finally, I run bootstrap builds/testsuites with this level of
optimization on an i686 every couple of days.  While there are more
failures than with the default flags, nothing striking shows up.
