Indeed, the interp is discussing the example in at the end of c14 in F2003.  It 
is not discussing F2008.  Bringing F2008 into the issue is unhelpful.

The Fortran 2008 feature is a total complete red herring that has nothing 
whatsoever to do with answering this interpretation request.

Sorry, but you are wrong.  People have the right to ask questions about the text 
of the current standard, and we have an obligation to answer them.

Since the interp was asking about the F2003 example and has nothing whatsoever 
to do with the F2008 intrinsic, this only shows confusion.

Since your NO vote is based on conflating John's example, unfortunately called 
HYPOT, with
  (a) the HYPOT intrinsic in F2008 draft,
  (b) the C libm function hypot(),
and
  (c) the IEEE 754-2008 (not IEC 60559!) function hypot,
it is very clearly based on a false premise.  Or three of them.
