It also compiles with current gfortran 4.3 if you use the option
  -fno-range-check
to force gfortran to ignore the numerical overflow.


But I think the problem is here:
  b = uword(int(65535,kind=4))

The uword() is a structure constructor. It is equivalent to write this as:
  b = uword(value = int(65535,kind=4))
or as
  b%value = int(65535,kind=4)
which converts automatically integer(4) to integer(2) without calling the
uword_assign_4 routine.

You really want to use:
  b = int(65535,kind=4)
without the structure constructor "uword". In this case your uword_assign_4
routine is called, which also gives not overflow and thus no error.
