Subject: [PATCH] Long awaited port for NetBSD/m68k was finally done by Mr.
 Mutsuki Nakajima. Since he is not subscribing the mailing list, I'm posting
 his patches by his request.  According to him, he has successfully compiled
 and passed the regression test on Mac SE/30 running NetBSD/m68k. Also,
 another person has reported that with the patches PostgreSQL is working on
 NetBSD/sun3 too. -- Tatsuo Ishii
