With the false positive, how do subsequent tests fail?  In particular
how does the pthread compatibility [pthread_create() works] test fail?
(config.log details please)

Exactly which tests do you have to disable to get good results
(using envirnonment flags to disable specific tests).
	env ol_cv_kthread_flag=no ./configure

(please add a platform hint with the appropriate environment flags)

The tests cannot be easily reordered.  It's likely that you'll
have to suffer with environment flags until 2.0 (which sports
new pthread detection support).

OpenLDAP is designed to be built using a ANSI C compiler.
Building with C++ compilers are not supported.  Your mileage
will vary.
