make of OL v2.2.6 fails on AIX v5.2 (maintenance levels 01 and 02) using C for
AIX v6. Make complains about MAXTHREADS being redefined in
libraries/libldap_r/tpool.c:

#> ./configure  --prefix=/usr/local --libexecdir=/usr/local/sbin
--enable-slapd 
--enable-slurpd --enable-dynamic --enable-ldbm=no

#> make depend
"tpool.c", line 48.9: 1506-213 (S) Macro name MAXTHREADS cannot be redefined.
"tpool.c", line 48.9: 1506-358 (I) "MAXTHREADS" is defined on line 65 of
/usr/include/sys/thread.h.

A workaround is to comment out line 48 in tpool.s but this may break builds on
other platforms.
