 Then it should be fine. OTOH it is ~10 lines of code to do the expansion =
 so it is not a big
 issue anyway; also others had come up with the same patch in the past to =
 solve the same

 Yes, because only the "standard" objdir patterns are supported; any =
 custom ones
 will need to be added manually to the list. Perhaps there is a =
 programmatic way
 to do this, but it is complicated and probably not worth it :-)
