2.5 build failure on OBS

HI!

As usual I'm using openSUSE Build Service to build openldap2 RPMs. This
smoothly works with 2.4.x.

But building 2.5 branch snapshot fails.

Maybe OBS compiler options are set pretty strict because it outputs:

[  147s] cc1: some warnings being treated as errors
[  147s] make[2]: *** [<builtin>: slapd-watcher.o] Error 1

You can look at the full build log with some warnings here:

Ciao, Michael.
