Subject: [PATCH] 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. |
|
