If there's no objection, I'll clean things up, removing all unnecessary
calls to STRERROR, using your workaround where its use might be
of help.

I've checked: all times the only function that ends up using STRERROR(),
i.e. ldap_pvt_get_hname(), any time it's called the value of the error 
message
is simply ignored, so I allowed to pass a NULL pointer to the error message,
resulting in no call to STRERROR().

I'm wasting time on this because a customer complained
about the gcc warnings...
