What is the status on this now? After reviewing the standard I think I am in
agreement with what this patch does. The standard is not exactly straight
forward interpret.
Do we have consensus yet on this? If so, I will commit for Paul.

I'm not 100% sure. The standard is indeed not very clear about it.
My feeling is that the standard forbids some of the things on the basis that
the compiler is not required to check those, but I should study the patch and
the standard again.
With the patch the following is not ambiguous:
+ SUBROUTINE s2(p2)
+ interface
+ function p2 ()
+ real p2
+ end
+ end interface
+ END
+ SUBROUTINE s1(p1)
+ external p1
+ END
This is based on the following: the first one is a function (well, that's
obvious) and the second one is a subroutine. But is this indeed clear?
Without IMPLICIT NONE the second could be equally well a real function, or do I
miss something subtle?

Go back to the thread on it. I did not seem able to satisfy the reviewer as to
my interpretation of the standard; since I could not see any other, I let it
drop. I'll unassign myself.

I think this effectively a duplicate of PR 34004.
The example of comment 0 is invalid (the specific functions have arguments
which are not distinguishable per the Fortran standard, see PR 34004). That can
distinguish them in practice does not count.
