I've get the most recent version of gunlib by "git clone" and it seems that the issue is resolved here. How should I proceed with my findutils?

Thanks for the report. In reality, this is a gnulib issue, so I have added bug-gnulib. Also, I'm not sure if gnulib has fixed the problem in the meantime, and findutils is just suffering from a stale gnulib release, or if it still exists in upstream gnulib. Are you in a position where you could help test building from git? With a recent gnulib.git checkout, it would be nice to know the results of: ./gnulib-tool --create-testdir --with-tests --dir=foo wchar stdio followed by configuring in the just-created foo directory and running 'make check' for your cross compiler setup. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
