Hi,
the change in src/sys/i386/include/ucontext.h (in struct __mcontext),
where "struct trapframe mc_tf;" was replaced by it's members
broke doscmd.
(The relevant files are
$FreeBSD: src/sys/i386/include/ucontext.h,v 1.3 1999/10/07 12:40:34 marcel Exp $
$FreeBSD: src/usr.bin/doscmd/signal.c,v 1.5 1999/09/29 20:09:18 marcel Exp $
$FreeBSD: src/usr.bin/doscmd/trap.c,v 1.6 1999/09/29 20:09:19 marcel Exp $
)
The following patch should fix it.
Bye, Philipp
