rm: update gnulib to get an fts fix for Cygwin+NWFS/NcFsd file systems
* NEWS (Bug fixes): Mention it.
As far as we know, this fix affects only Cygwin with NWFS or NcFsd
file systems. See these:
http://git.sv.gnu.org/cgit/gnulib.git/commit/?id=
71f13422f3e634
http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739
http://cygwin.com/ml/cygwin/2011-10/msg00365.html
* src/system.h (ENODATA): Remove fall-back definition, now that
gnulib provides one. Caught by the sc_prohibit_always-defined_macros
syntax-check rule.
Also remove now-irrelevant "Don't use bcopy..." comment.
