Actually, this isn't an i386 remote target: it's my i386 Linux host.  I'm sorry 
if I sent you off in the wrong direction (I guess I should have been more 
specific than just "i386").

Just to be clear on what the problem is: recurse.exp on an i386 Linux host is 
all PASS; I just don't understand why it works the way it does.

There are actually two things that don't make sense to me:

1. Why the i386 reports a watchpoint hit when reaching the watchpoint scope del 
breakpoint if the watchpoint has been hit previously (but not otherwise).

2. Compare the "Mimicking recurse.exp" and "Watch on return statement" examples 
in my previous e-mail: in both cases GDB notices that the watched variable goes 
out of scope, but stops only in the first case (where out of scope is detected 
by watchpoint_check) and not in the second case (where out of scope is detected 
by insert_bp_location).
