The problem is that local.mk is (for now) an automake source, and automake doesn't support := because it is designed to create makefiles portable to more than just GNU make. Maybe down the road automake will require GNU make, at which point we can rely on GNU make-isms outside of maint.mk, but for now, we try to limit the GNU make extensions to the stuff that doesn't impact automake. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
