Why are you reporting this to the Automake mailing list?  Ralf kindly
pointed you in the right direction, and asked you to provide details
_if_ you still think Automake is in a position to help.  I don't see
you suggesting what Automake should be doing differently, instead, I
see a pax bug report sent to the Automake list.
