To work around the bug temporarily, you can install the following
patch into lib/priv-set.h and lib/priv-set.c (but don't patch the
other files unless you have developer tools).
I have installed this patch into gnulib, so the problem should be
fixed more permanently in the next tar release. Thanks for reporting
the problem.
priv-set: Don't assume that priv.h exists merely because getppriv does.

* m4/priv-set.m4 (gl_PRIV_SET): Check for priv.h.
* lib/priv-set.c: Do nothing unless HAVE_PRIV_H.
* lib/priv-set.h: Likewise.
* tests/test-priv-set.c: Likewise.
