config.status doesn't exit

[Pavel Roskin]

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.

Regards,
Pavel Roskin
