+# FreeBSD 2.2.5 comes with a Chris Provenzano Pthreads
+# package, # but it must be manually built.  See pthread(3) for details.
+# OpenLDAP is compatible with this version, uncomment the following
+# options:
+#
+#THREADS= -DPOSIX_THREADS -D_THREAD_SAFE -DPTHREAD_PREEMPTIVE
+#THREADSLIB= -lc_r
+#
+# Some versions of FreeBSD support the gcc option "-pthread" to
+# link with -lc_r.  On those systems, uncomment the following:
+#THREADSLIB= -pthread
+#
 #
+# If the only thread package available is only Draft 4 compliant,
+# you can try the following:
+#THREADS= -DTHREAD_MIT_PTHREADS -D_THREAD_SAFE -DPTHREAD_PREEMPTIVE

+# Note:
 # LDAP has a problem with the idea of implicit vs. explicit yields
 # in call conversion threading packages, like the MIT pthreads
-# package.  Rather than resolve this globally, I have marked the
-# threading as "preeemptive", even though it is technically not.
