OK, I seem to have missed Kurt's e-mail. I just went back and read it. I 
am of 
course sure he is right. But I certainly cannot untangle how it all works 
together (maybe he could explain please?).

OK, that I see (in the latest draft):
"If the reference is consistent with a nonelemental reference to one of 
the 
specific interfaces of a generic interface
that has that name and either is in the scoping unit in which the 
reference 
appears or is made accessible by a
USE statement in the scoping unit, the reference is to the specific 
procedure 
in the interface block that provides
that interface. The rules in 12.4.3.4.5 ensure that there can be at most 
one 
such specific procedure."

But when I look in 12.4.3.4.5, I see:
"This subclause contains the rules that shall be satisfied by every pair 
of 
specific procedures that have the same
generic identifier within a scoping unit."
As far as I can tell, SUBR1 and SUBR2 both have the same generic 
identifier 
within subroutine S? Where is there a distinction between generics 
accessed 
by USE association and those by host association?

Is there a compiler that actually implements what Kurt says was the 
intention?

Best,
Aleks
