I'd much rather write this as a probe to see if linking with -rt makes a difference, and only add it when it matters, than trying to blindly add it (the pre-patch version) or to blindly exclude it for some platforms (the post-patch version). I also wonder if gnulib has some help on this front. NACK to this version while I investigate. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
