$NetBSD: patch-ae,v 1.8 2013/12/06 07:27:15 mef Exp $

- ERROR: [check-portability.awk] => Found test ... == ...:

- automake-1.13 compat.

- add missing AM_PROG_CC_C_O that automake wants for the yacc
  sources.

- allow a different default serial/parallel port to be specified
  which is useful for pkgsrc (since we have defaults for various
  platforms available and they're not the same for different
  MACHINE_ARCH's in NetBSD).
