darcs patch: Create ar archives with unique object names.

Hi, Please disregard my last mail, I managed to introduce a compile error with my last cosmetic changes. Here's the patch again (amended). Bertram Sat Jun 6 17:37:10 CEST 2009 Bertram Felgenhauer <int-e@gmx.de> * Create ar archives with unique object names. Posix does not specify whether this is supported, and GNU ar has trouble with them. See #318 for more info.
