exit

[Simon Josefsson]

Building all modules leads to this warning:

gnulib-tool: warning: module obstack depends on a module with an incompatible 
license: exit

I took a look at this.  Here is the 'exit' module definition:

,----
| Description:
| exit() function: program termination.
| 
| Files:
| 
| Depends-on:
| stdlib
| 
| configure.ac:
| 
| Makefile.am:
| 
| Include:
| <stdlib.h>
| 
| License:
| GPL
| 
| Maintainer:
| Bruno Haible
`----

The stdlib module is LGPLv2.1+.

Is the 'exit' module really useful, other than transition for old code
when the exit module provided something?  It was changed to this content
back in 2007.

How about adding this to the 'exit' module:

,----
| Status:
| obsolete
| 
| Notice:
| This module is obsolete. It will be removed on 2011-01-01.  Use 'stdlib'.
`----

Second to that option, how about changing the license to 'unlimited'
since the 'exit' module is just meta information?
