2.3.11 on AIX 5.2

[Albert Chin <openldap-devel@mlists.thewrittenword.com>]

Anyone have 2.3.11 running _with_ module support on AIX? Using the
stock 2.3.11, compiled with our version of Berkeley DB 4.2.52,
Cyrus-SASL 2.1.20, OpenSSL 0.9.7b, and libtool 1.5 (for ltdl):
  $ cd /opt/build
  $ gtar zxf /opt/src/db/openldap-2.3.11/src/openldap-2.3.11.tgz
  $ cd openldap-2.3.11

I think the problem is due to the way the AIX linker exports symbols
(not the same as other unices). If I manually export all symbols, then
slapd starts ok (relinking with -bexpall gives
ldap_pvt_thread_pool_purgekey as unresolved). When linking slapd,
libtool doesn't link slapd against the libldap_r.so but libldap_r.a
which probably gives some of the ldap_ errors above. Ditto for
liblber.so.

Note I am using -brtl.
