Where are you doing this?  AFAIK, the list of intrinsics is constructed
when gfortran is compiled not when you execute gfortran.  At runtime
we need to be able to regenerate the expected list of intrinsics from
the master.  To me, this means we need to tag each specific and generic
intrinsic procedure with a standard.
