Due to the changes introduced by the Automake migration, system tests requiring Python (chain, pipelined, qmin, tcp), dynamic loading of shared objects (dlzexternal, dyndb, filter-aaaa), or LMDB (nzd2nzf) currently do not work on Windows. Temporarily disable them on that platform by moving them from the PARALLEL_COMMON list to the PARALLEL_UNIX list until the situation is rectified.
