I did not differentiate between 'first', 'last' or 'any' at all.
I just was out of ideas which one of the zillion methods restricting the shell
block execution to a single file would be enough cross-UNIX compatible.
I found out now that 'break' is documented by "Limitations of Shell Builtins"
as compatible, therefore here is a patch copying the permissions of the FIRST
file of $ac_file_inputs.
I always thought I am able to code shell scripts...
