Subject: [PATCH 71/74] Make "exit" take a return code.
|
|
|
|
This adds "exit" with a return code. With this patch, any "exit"
|
|
command /may/ include a return code, and on platforms that support
|
|
returning with an exit status, we will do so. By default we return the
|
|
same exit status we did before this patch.
|
|
