The last one I was unable to work around in any sensible manner: when linking, clang fails with

This seems to be a well-known issue[1] with no solution in sight; passing CFLAGS='-rtlib=compiler-rt' to configure allows the compilation to succeed but, yeah, way gross.
And gnulib just fixed things to avoid tickling that clang bug: http://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=04441fd8 Work around LLVM bug 16404, which is still not fixed. https://llvm.org/bugs/show_bug.cgi?id=16404 Problem reported by Nelson H. F. Beebe. Shall I go ahead and update the gnulib submodule to the latest, and see if you can get further with your clang tests as a result? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
