False alarm: a flag remained ill-defined (ie-std=f2003 instead 
of -std=f2008) in a component of the Windows version...

Now the source code is compiled nearly in the same way (see point 2/2) 
in Linux and Window systems.


2/2) Although as suggested by Tobias Burnus 12/05/2011 17:45:15 UTC,  
in "Bug ​​45823 - Bogus warning for intrinsic module procedures", works 
very well, perhaps, there would be another way to remove the 
warning shown there, e.g.


module m_test
  use ISO_FORTRAN_ENV
  implicit none
  public
  integer, parameter :: irp = REAL_KINDS (2)
end module m_test
!
program test
 !use m_test, only : irp  ! Tobias Burnus suggestion 2011-05-12 10:35:23 UTC 
  use m_test              ! bogus warning?
  implicit none
  real (irp) :: x
  x = 1.0_irp
end program test

Now I'm not absolutely sure, but this warning had not seen before in the 
Linux version for quad-core.
