[patch] Pmode/ptr_mode fix for except.c

[Eric Christopher]

When Pmode/ptr_mode are different we need to do the expansion and extend
this way:

2002-09-17  Eric Christopher  <echristo@redhat.com>

        * except.c: Use ptr_mode in expansion.  Handle case
        where Pmode != ptr_mode.

OK for somewhere?
