Yep, they make good sense.

I know what you mean, now :)

Humpf, yes, right. That was pretty mindless of me...

Here is what I propose to check in. Do you think I should remove
the INHERIT for the to_kill method as well?

2009-03-17  Joel Brobecker  <brobecker@adacore.com>

        Add a target_ops parameter to the to_kill method in struct target_ops.
    
        * target.h (struct target_ops): Add a "target_ops *" parameter to
        method to_kill.
        (target_kill): Remove macro. Add declaration.
        * target.c (debug_to_kill): Delete, no longer necessary.
        (target_kill): New function.
        (update_current_target): Update the call to de_fault for field
        "to_kill".
        (setup_target_debug): Do not set current_target.to_kill.
        * gnu-nat.c, go32-nat.c, hpux-thread.c, inf-ptrace.c, inf-ttrace.c,
        linux-nat.c, monitor.c, nto-procfs.c, procfs.c, remote-m32r-sdi.c,
        remote-mips.c, remote-sim.c, remote.c, windows-nat.c: Update
        accordingly.
