[Bug fortran/28484] New: system_clock with real-type count_rate does not compile

["tobias dot burnus at physik dot fu-berlin dot de" <gcc-bugzilla at gcc dot gnu dot org>]

When compiling the following program,
------------------
  real :: cntrate
  call system_clock(count_rate=cntrate)
end
------------------
gfortran (4.2.0 20060725) shows the error:

  call system_clock(count_rate=cntrate)
                              1
Error: 'count_rate' argument of 'system_clock' intrinsic at (1) must be INTEGER

Expected: No error is shown as the Fortran standard (quoting from Fortran 2003)
allows this:

--------------------------------
13.7.117 SYSTEM_CLOCK ([COUNT, COUNT_RATE, COUNT_MAX])

Arguments.
COUNT  (optional)   shall be scalar and of type integer.
COUNT RATE (optional)  shall be scalar and of type integer or real.
COUNT MAX (optional) shall be scalar and of type integer.
--------------------------------
