Talking about data structure alignment:
I have often wanted an optimizing compiler that could take
struct { long a; int b; long c; char d; }
which is usually mapped into bytes as AAAABBxxCCCCDxxx
(on a machine where misaligned accesses are penalized)
and make it into AAAACCCCBBDx.

    aglew@gswd-vms.gould.com    - if you don't
    aglew@gswd-vms.arpa 	- if you use DoD hosttable
    aglew%mycroft@gswd-vms.arpa - domains are supposed to make things easier?
