REAL_KINDS: a compilation error in Windows but not in Linux ?

[Jorge D'ELIA]

Hi there,

In a notebook (Pentium(R) Dual-Core CPU T4400, 2.2 GHz)  
with windows 7 Starter (2009), I found a compilation 
error that does not appear with the Linux version. 
The sample code, compiler version and output are:

module m_test
  use ISO_FORTRAN_ENV
  implicit none
  public
  integer, parameter :: iin = kind (1)
  integer, parameter :: isp = REAL_KINDS (1)
  integer, parameter :: idp = REAL_KINDS (2)
  integer, parameter :: iep = REAL_KINDS (3)
  integer, parameter :: iqp = REAL_KINDS (4)
end module m_test

C:\Users\TEST\gfortran --version
GNU Fortran (GCC) 4.7.0 20110419 (experimental) [trunk revision 170140]

C:\Users\TEST\gfortran -Wall -std=f2003 -c m_test.f90 m_test.f90:6.29:

  integer, parameter :: isp = REAL_KINDS (1)
                             1

                             1

Jorge.
