From 8e6eb00a8e1aaa599e9a73fe473d0211c68784ec Mon Sep 17 00:00:00 2001
From: jb <jb@FreeBSD.org>

Subject: Move _JBLEN definition to <machine/setjmp.h> like on NetBSD. Remove
 definitions for architectures that we don't have libc MD source for.

Change 'int' to 'long' in sigjmp_buf and jmp_buf structures so
that they are suitable for the register size on both i386 and alpha.
Although FreeBSD defines these structures differently to NetBSD,
the element size is now the same.

If Bruce doesn't like this [8-)], we'll need to add a typedef to
each <machine/setjmp.h> and use that in <setjmp.h>.
