By the way, your c84de70 (excluded_1(): support exclude files in index,
2009-08-20) looks broken.  What happens when the exclude pattern wants a
directory but specifies it with a wildcard?

The safest and sanest first step is to just change DT_UNKNOWN (which
clearly is a wrong thing to pass) to NULL to keep the current behaviour,
but it probably makes more sense to do the second step at the same time to
pass a pointer to an int that holds DT_UNKNOWN to avoid triggering that
broken codepath.
