Re: No libldap_r in OpenLDAP 2.5 - use LDAP_API_FEATURE_X_OPENLDAP_REENTRANT from ldap_features.h

Hello Tom,

I run Linux from Scratch system.  All old binaries, are linked with
libldap(_r)-2.4, all new things get linked towards libldap-2.5 .  So
the configuration step always sees libldap-2.5 as most current (and its
header files).  I can in theory point the build process to versioned-
headers, but I do not have to.

The problem here is, that libldap_r-2.4, libldap-2.4, and libldap-2.5
are installed on the system.  I want that libpq.so is not linked with
libldap_r-2.4, but with libldap-2.5.

Greetings
