PATCH: enable Ada test suite

[Richard Kenner]

    If it's intentionally not portable, perhaps someone could change the first
    line of the script to be:

        #!/bin/bash

    instead?  I doubt this would significantly reduce its current portability,
    and it would give poor confused people with Bourne shells some clue as to
    what they need to do to get it to work.

No, because bash isn't always in /bin.  On non-Linux systems, it's usually
in /usr/local/bin, for example.
