Not in the log I posted. isatty is NOT that large, so what ever this is, is after isatty in the executable. I wonder if something forgot to pick up the /usr/obj libraries, since the HOST system *IS* compiled with -march=pentiumpro. This is valid, isn't it? (to compile on one box, and install on another with DIFFERENT /etc/make.conf settings)? >>>>>>>>>>>>>>>>>> Original Message <<<<<<<<<<<<<<<<<< On 3/12/01, 12:12:39 PM, John Baldwin <jhb@FreeBSD.ORG> wrote regarding Re: cputype=486: > On 12-Mar-01 Larry Rosenman wrote: > > * Larry Rosenman <ler@lerctr.org> [010312 05:53]: > >> * Kris Kennaway <kris@obsecurity.org> [010312 02:35]: > >> > On Mon, Mar 12, 2001 at 02:31:35AM -0600, Mike Pritchard wrote: > >> > > >> > > Somewhat.
