This is something we recently fixed in rsync:  the setgroups() call
doesn't always allow a NULL argument.  We bypassed the problem by
calling setgroups() with the single gid as our arg:

    if (setgroups(1, &gid)) {

That would work in the distcc code as well.  I also moved the call to
setgid() prior to the setgroups() code, just because it seemed like a
better order of events to me (in the rsync code).
