NetBSD x20.i.nabechan.org 1.5Y NetBSD 1.5Y (X20) #118: Tue Oct 23 18:12:45 JST 2001     nabe@x20.i.nabechan.org:/usr/local/src/NetBSD/src/sys/arch/i386/compile/X20 i386

>Description:
The NetBSD execute the FreeBSD 4.4-RELEASE binary as
 a linux binary, so I can not execute.
The reason is related to the integration of binutils 2.11.2 in FreeBSD.
http://www.FreeBSD.org/cgi/cvsweb.cgi/src/contrib/binutils/bfd/elf.c.diff?r1=1.3.6.4&r2=1.3.6.5

>How-To-Repeat:
Get the binary from FreeBSD 4.4-RELEASE tar balls and execute it.
