Under UnixWare 2.x, alloca is in the UCB library (libucb.a ?). The easist way
to link in alloca is to extract it from libucb.a and either link in the
alloca.o file or put it into the libgen.a library and the link in via -lgen.
Why now just link in lubucb.a you ask? The are routines in libucb.a that you
do not want to get linked into the object in place of the regular routines
with the same name. I have ran my UnixWare 2.x system (when I had it) with
alloca in libgen.a with out any problems.

This was the setup I used to compile Postgres 6.3.x when I had UnixWare 2.x.
[Hmmm.... It looks like I should put together a 486 box to run Unixware 2.x
on so that I can test new versions of PostgreSQL on it].
