+ fstatat: work with cross-compilation
+ Problem reported by Ludovic Courtès in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-11/msg00136.html>.
+ * m4/fstatat.m4 (gl_FUNC_FSTATAT): When cross-compiling, report
+ "cross-compiling" and assume the bug is present. Replace
+ FSTATAT_ZERO_FLAG_BROKEN with HAVE_WORKING_FSTATAT_ZERO_FLAG with
+ an inverted sense, to be more conservative about our assumptions.
+ * lib/fstatat.c (rpl_fstatat): Adjust to renamed macro.
