> Bison was used to support gcc, which is the compiler used in 3.x. The > version of gcc 3.2 uses is also old, so we need a matching bison. Close, but not quite. Bison was brought in because gcc-2.7.x (or maybe it was 2.6.x) would not compile with Byacc. 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
