Hmm. That can probably be worked around with an entry in
Makefile.custom, though I haven't looked at the specific usage.

Fantastic.

Forwarding the patches is good. Is there anything in them which could
possibly damage a non-alpha machine? If not, and if they are on the
right track (they must be, since things actually work finally :) then
they should eventually end up in our main tree.
In glancing through the patches, I notice that one change is to pass
"Datum" to all ADT functions which take a char, int2, or int4. That
certainly makes the code uglier, but I can see that fudging the calls
as we did earlier might have led to trouble.
In the meantime, they could end up in Linux RPMs as patches to the
pristine distribution, and could be in new RPMs released through
RedHat. They will be very excited (or at least as excited as they
get... ;)
