Yes, but only because my machine had the libc_private.h chunk which I
forgot in the diff.

I would like to merge these changes to RELENG_8, RELENG_7, and RELENG_6
if possible.  Anything which depends on dbus (e.g. GNOME) will just
crash without them.  In the meantime, I have hacked libpthread-stubs,
but I really think this is the more correct fix.


Thanks for the review.
