You'll need to implement the real(10), real(16), and integer(16)
versions.  If gfortran (on some target) provides any or all of
these types, then we need intrinsic procedures.

This is a bug with many of the intrinsics procedures because
the procedures predate gfortran's ability to do these kind
types.

FX mentioned that he wanted to clean up the library.  We should
make sure all the intrinsics are implemented for all of the 
valid kinds.
