It has been a long time since this report, and regular testing by Peter
hasn't (AFAIK) tickled similar failures in any modern Automake+Cygwin
combination.  So I'm closing this report, to avoid keeping the bug
tracker cluttered.

Peter, if I'm wrong and you're indeed seeing similar issues, feel
free to re-open this report.

Thanks,
  Stefano
