Thanks, Uri, a great work have been done to chaise all this annoying
warnings. Hope those will end up in the master tree.

In you "[PATCH 16/35] winbind_nss_freebsd: fix a const discard warning"
though you change the signature of the function:

__getgroupmembership(const char *uname, gid_t agroup, gid_t *groups,
        int maxgrp, int *grpcnt)

which should be avoided. Need to fix this warning somewhere else.

As for the Clang being liberal regarding unknown options we use the
following trick:

There are a lot of small fixes like this in the FreeBSD Samba port, hope
they'll find their way into master as well.

With regards,
Timur Bakeyev.
