Ada policy

[Richard Kenner]

    for example, fixes to bugs with public non-ACATS testcases don't get
    them added to the testsuite (and there is no harness to add them to)
    although a fair number of such testcases have been posted to the lists
    over the years which ought to be in the testsuite.

There are two problems here.  First, there is no testsuite harness to
add the available test cases (as you say) and second that nearly all
of the test cases are proprietary code.

If somebody volunteers to do the former, that problem will go away.
But the second problem is more serious, especially if you enlarge
the set of changes that need test cases to front-end changes.
