That's a bug in the user's configure.ac script for not quoting things correctly in the first place. Autoconf can't work around every piece of bad code thrown at it, and my recommendation would be to fix rezound rather than trying to throw more workarounds in autoconf to avoid this bad code at the expense of penalizing performance on good code. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
