See my answer to Jim. I MEANT to compile with a HOST system that has=20 -march=3Dpentiumpro executables, and compile a new world with CPUTYPE=3D= i486=20 or=20 no CPUTYPE and expect the new code to run on the 486, correct method?=20 LER >>>>>>>>>>>>>>>>>> Original Message <<<<<<<<<<<<<<<<<< On 3/12/01, 12:49:50 PM, John Baldwin <jhb@FreeBSD.org> wrote regarding = Re:=20 cputype=3D486: > On 12-Mar-01 Larry Rosenman wrote: > > Not in the log I posted. isatty is NOT that large, so what ever thi= s is, > > is after isatty in the executable. > *sigh* > isatty() is in libc.
