First, I should note that the URL does not lead to a list
of tests that fail.  It points to a list of intrinsic
subrprogram where the Fortran standard specifically 
calls out behavior for dummy arguments associated with
a size zero actual argument.  No tests were written
or performed.

Item 1) is covered by PR 54613
Item 2) is now PR 84697.
Items 3)-5) do not exhibit any unexpected behavior.
Item 6) concerns old g77 compatibility routines
I won't check those as no one should be using these
routines.

This PR should be closed, but I'll leave that up to
others.
