I'll rename
   setlocale, textdomain, and bindtextdomain
in include/ac/localize.h to
   ldap_pvt_<function name>
so the definitions cannot break headers in /usr/include/, and move
   #include <EXTERN.h>
   #include <perl.h>
   #undef _ /* #defined used by both Perl and ac/localize.h */
   #include "asperl_undefs.h"
to the top of the back-perl files.

Someone who can test OpenLDAP on Windows can remove asperl_undefs.h
later if that file turns out to be obsolete.  If not, the fix may
have to be bigger, since asperl_undefs.h may depend on a new macro
from portable.h which will now be included _after_ asperl_undefs.h.
