Looks great and fixes also comment 10's test case.

I tried to test for the "intrinsic elemental" of comment 2's standard quote.
That works without "elemental" in the INTERFACE but not with. However, the
standard states for "acos": "Class. Elemental function." Nonetheless, gfortran
prints:

  Error: Interface mismatch in procedure pointer assignment at (1):
         Mismatch in PURE attribute"

for

intrinsic acos
interface
  elemental real function oo(x) ! Works (and should work) without "elemental"
    real, intent(in) :: x
  end function
end interface
procedure(oo),pointer :: bar
bar => acos
end
