[Bug fortran/33950] New: Warning missing for function result not set

["fxcoudert at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

In the first case below, a warning should be emitted just the same as the
second case... Types other than character are not affected, because for them
the middle-end will do the job anyway.

$ cat s.f90
function pop() result(item)
  character(len=0) :: item
end function pop
$ gfortran s.f90 -c
$ cat t.f90
function pop()
  character(len=1) :: pop
end function pop
$ gfortran t.f90 -c
t.f90: In function ?pop?:
t.f90:1: warning: Function does not return a value
