I don't know which code makes your configure look in /usr early; if there are any -L/usr/lib or -L/usr/lib64 instances on the link command line or in what libtool generates, then that is usually an error. Otherwise, I'd hope that the macro looks in directories specified with -L before any default ones; and using gcc's library search path for the default ones sounds sensible, but allowing to prefix all directories with a sysroot specified at configure time would still be a very helpful improvement. Arbitrary reordering of directories OTOH sounds like it would only lead to more random breakage in other situations. Cheers, Ralf
