    You are correct.  And that is the most bogus version of "its not a
bug it is a feature" I have ever seen.

    There is no fixed by fixed division operation defined for
Fixed_Type or its parent, so whether or not it is a derived type is
irrelevant.  In any case the division operation for _universal_fixed_
that applies here is defined in STANDARD, and will be visible without
the use clause.

    Give the vendor fifty lashes with a wet noodle, served with heaping
amounts of supercilious scorn. ;-)
