int8 type -- call for porting results!

Hi. A month or two ago I put an int8 data type into Postgres. Aside from
being useful on its own, it could also form the basis for other types
needing extended range, such as money, decimal, and numeric types (the
last two are SQL92 types).

Anyway, I implemented it on a gcc/x86/Linux machine, and we will need to
ensure that it works on other platforms. If you are doing any work at
all with a post-v6.3.2 source tree on another platform/OS combination,
can you please look at the results of the int8 regression test, or run
that test on your own, and let me know if it worked? If it didn't work,
then we should either put it on the list of things to do or make it work
in time for v6.4. But at the moment I don't know either way.

btw, there is a chance that the Alpha port will work since I coded for
it and I used to work on Alpha machines...

TIA
