Portability just means there should be a fall-back implementation which
uses the ldap_pvt_thread_*() locking functions. Or if it is made a
separate library from OpenLDAP, it could use macros which default to
pthread_*() but could be overridden to use ldap_pvt_thread_*().
No wonder why I prefer Java :) ...
Macros... Sad memories :/
