2.95.3 update

[Bernd Schmidt]

Just a quick update what's going on with 2.95.3.
There are two open problems:  the sjlj eh problem which needs to be fixed,
and a regression on a powerpc target found by David Edelsohn.

I'm still working on the sjlj eh problem.  I managed to convince myself that
the backport of Richard's fix will correctly fix the problem.  Unfortunately
it triggers an -fPIC bug on sparc which means we can't build libgcc.  I have
a fix for this which I'm testing at the moment.
