Here are all of the Critical Angle, Inc. patches to the University
of Michigan LDAP server, version 3.3.

In addition, there are my patches to make it work with Draft 4
Pthreads, and my patches for FreeBSD platform support.

I have also added patches for FD_SETSIZE to be used when a select
fd count is required, in place of getdtablesize().  Using getdtablesize(2)
is wrong, except on systems which do not have a specific FD_SETSIZE
value (on most such systems, FD_SETSIZE will be defined as a call to
getdtablesize(2)).

In the FreeBSD platform support files, I also defined PTHREAD_PREEMPTIVE
for MIT Pthreads.  This is because there is an apparent misunderstanding
on the part of the LDAP authors about the difference between explicit
and implicit yield-based threading.

Someone should turn this into a "port" (but not me).
