No, but it IS fixed in m4.git branch-1.4, and I hope to release 1.4.16 this week. The latest m4.git also works around the glibc bug on all architectures (except SSE4.2) where strstr() could have false positives on certain periodic needles. http://git.sv.gnu.org/cgit/m4.git/commit/?h=branch-1.4&id=5e763da32 -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
