    How about letting the kernel return ENOEXEC instead of ENOENT? It would
    give the luser just the little extra hint about converting their files to
    Unix format.

    $ ls
    testscript
    $ head -1 testscript
    #!/bin/sh
    $ ./testscript
    bash: ./testscript: No such file or directory

    versus

    $ ./testscript
    bash: ./testscript: Exec format error

    I haven't got a clue what Posix requires though.
