Correct - so it is essential that AC_CONFIG_MACRO_DIR cause AC_CONFIG_MACRO_DIR_TRACE to be traced. That way, both old libtool (which sed's for the single instance of the old name) and new libtool (which traces for one or more instances of the new name) will both get the same answer; and furthermore, that the answer agrees with aclocal from automake 1.14 on _which_ directory is the primary directory that can be modified by installing updated m4 files, vs. secondary directories that can be searched but not modified. And that's precisely what I implemented. -- Eric Blake [email protected] +1-919-301-3266 Libvirt virtualization library http://libvirt.org
