! Checks the fix for PR33541, in which a requirement of

! F95 11.3.2 was not being met: The local names 'x' and

! 'y' coming from the USE statements without an ONLY clause

! should not survive in the presence of the locally renamed

! versions. In fixing the PR, the same correction has been

! made to generic interfaces.
