Nobody really wanted to maintain Bison in the base tree, thus it hasn't gotten any attention. Bison 1.25 works for ``make world'' and that is suffient for FreeBSD's base needs. It has nothing to do with gcc-2.7.2 (and old version) also requireing an old version of Bison (over just requiring Bison). > -current uses egcs.

We aim to depend on as few GPL licensed tools for building the system as possible. -- -- David (obrien@NUXI.com -or- obrien@FreeBSD.org) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
