When running configure to install OpenLDAP 1.2.7, also the previous versions, a
couple of the tests for threads give false positive results.  Starting with
checking for pthread_create with -kthread, and the next two tests if I remove
the previous test, these tests succeed and following thread tests fail aborting
the configure process.  If the HPUX thread tests are moved to before the
checking for pthread_create with -kthread test OpenLDAP build successfully.  I
haven't checked to see if moving this test will break any of the other operating
systems.  I am running 64-Bit HP-UX 11.00 with ANSI C and aC++ compilers.
