* config/i386/i386m3.mh (NAT_CLIBS): Add -lmachid and -lnetname.
* m3-nat.c, config/nm-m3.h: #if 0 REQUEST_QUIT stuff.
* m3-nat.c: Pass argument to return_to_top_level.
Declare m3_kill_inferior before use.
(port_chain_insert): In "can't happen" case, abort rather than
setting `mid' to large decimal constant (which gcc warns about).
(get_thread_name): Use cast to convert const char * to char *.
(add_mach_specific_commands): #if 0 "thread break" command.
(m3_trace_him): Call push_target.
(mach_really_wait): New argument pid; remove unused
variable pid.
(intercept_exec_calls): Call target_terminal_init and
target_terminal_inferior once the child execs.
* infrun.c (proceed): Pass argument to PREPARE_TO_PROCEED.
