The patch makes no distinction between address-size
and offset-size in the dwarf2, but that is
an essential distinction, I think. 
I think the patch as written
will break alpha-64-bit-pointers-using-dwarf2 in dwarf2read.c

That is, it will break
any non-sgi target with 64bit pointers and dwarf2, 
as *only* SGI extended offsets/lengths in dwarf2 to 64bits for
64bit pointer apps.  And the patch makes no provision for
the coming dwarf2 revision with its compatible allowance
of 32-bit-offset and 64-bit-offset dwarf2 in a single
object file.

I believe this is very easily dealt with.

I hope to get to this to suggest a revised patch soon, but
of course, promises are worthless :-)
