Re: config.status doesn't exit

[Akim Demaille]

| Hello!
| This program:
| 
| #! /bin/sh
| tmp=`exit 1`
| echo "I'm alive"
| 
| prints "I'm alive" under all shells except ash. But config.status uses
| this construct when checking existance of the input files and expects to
| exit in all shells.
| 
| The patch is attached. It also included a test case.
| 
| ChangeLog:
|         * acgeneral.m4 (_AC_OUTPUT_FILES): Ensure that config.status
|         exits if any input file is missing.
|         * tests/semantics.m4 (missing templates): Test it.

Great patch, thanks a lot Pavel.  Apply.

Please, try to document ash's limitation too.  Don't forget to include
the version of ash (if you know how to get it, I couldn't find it),
it's been fixed since:

~/src/bison % sh /tmp/foo.sh                                      nostromo 9:02
I'm alive
~/src/bison % ash /tmp/foo.sh                                     nostromo 9:02
I'm alive
~/src/bison % zsh /tmp/foo.sh                                     nostromo 9:02
I'm alive
