Hi, I am trying to compile ROMS (available from http://www.myroms.org/) and am receiving the following error

cd Build; f95 -c -u -U -xarch=v9 -openmp -fast mod_forces.f90
f95: Warning: -xarch=native has been explicitly specified, or implicitly specified by a macro option, -xarch=native on this architecture implies -xarch=v8plusb which generates code that does not run on pre UltraSPARC III processors

A code snippet from initialize_forces is

SUBROUTINE initialize_forces(ng, tile, model)
!
!=======================================================================
! !
! This routine initialize all variables in the module using first !
! touch distribution policy. In shared-memory configuration, this !
! operation actually performs propagation of the "shared arrays" !
! across the cluster, unless another policy is specified to !
! override the default. !
! !
!=======================================================================
!
USE mod_param
!
! Imported variable declarations.
!
integer, intent(in) :: ng, tile,model

Can anyone shed some light on why
f95: Sun Fortran 95 8.2 Patch 121019-05 2006/12/08
complains about this bit of code.

Thanks,
Simon.
