You self-built from m4.git, but built from the master (experimental) branch instead of branch-1.4 (stable releases); unfortunately, the experimental branch is just that, and doesn't yet play nicely with autoconf. I should probably find a way to reject any m4 version at autoconf's configure time if it doesn't support GNU extensions; meanwhile, I should also find time to fix m4.git to make the experimental branch not regress in relation to released m4. -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
