+ * mi/mi-main.c (run_one_inferior): Add function description.
+ Make ARG a pointer to an integer whose value determines whether
+ we should "run" or "start" the program.
+ (mi_cmd_exec_run): Add handling of the "--start" option.

* remote-notif.h (REMOTE_NOTIF_ID): New enum.
-stack-list-variables now accept an option "--skip-unavailable".
When used, only the available locals or arguments are displayed.
+ ** The -exec-run command now accepts an optional "--start" option.
+ When used, the command follows the same semantics as the "start"
+ command, stopping the program's execution at the start of its
+ main subprogram.

* New system-wide configuration scripts
A GDB installation now provides scripts suitable for use as system-wide
configuration scripts for the following systems:

Starts execution of the inferior from the beginning. The inferior
exits. In the latter case the output will include an exit code, if
the program has exited exceptionally.
-When no option is specified, the current inferior is started. If the
+When neither the @samp{--all} nor the @samp{--thread-group} option
+is specified, the current inferior is started. If the
@samp{--thread-group} option is specified, it should refer to a thread
group of type @samp{process}, and that thread group will be started.
If the @samp{--all} option is specified, then all inferiors will be started.
+Using the @samp{--start} option instructs the debugger to stop
+the execution at the start of the inferior's main subprogram,
+following the same behavior as the @code{start} command
+(@pxref{Starting}).
