That being said, Bernhard, I suppose it would be worthwhile standardizing
some
configuration settings, seeing as despite our implementation differences, we
seem to largely support
target? That way we could at least free up some cpu cycles to work more quickly
on steps 2,3, and 4
Thoughts?

Hey all-
Patch to reduce the alignment constraints on ia64 elf core headers.
From what I can see
this is going into our reserved
memory, it saves us 3K (4K vs 1K alignment). Tested successfully by myself on
several ia64 boxes.
Thanks Regards
Neil
