Recently we had to deply OpenLDAP 2 on AIX (4.3 I think); after some
fighting I succeeded in compiling it with threads and with db-3.3.11;
it passed all the tests and I was able to load the db (small load
in the order of thousands of entries) and read from/write to it for a 
while without significant failures.  I compiled it with gcc 2.95.2,
and needed to explicitly set -lpthread -D_THREAD_SAFE otherwise no
reasonable thread settings were automatically detected; btw, I got these
options from db3's makefile after successfully configuring it.

(Hint to users, even if I might well be reinventing the wheel:
on AIX ALWAYS use --disable-shared !!!!).

Up to your experience, do you think this is going to be dependable?
