This looks fine to me. Perhaps change the comment to "Propagate
'executable' attribute of first input file." Note also that you can access
the first element of $ac_file_inputs as so:
ac_first_input=`set X $ac_file_inputs; echo $[2]`
It is a question of personal test whether this is a clearer or more obscure
method of accessing the first file. It is certainly a bit slower since it
invokes a subshell. (Note that the $[2] becomes $2 in the generated
configure script.)
