#670: commit 166d77a440a5 and b5f8b4ff16fb does not compile with gfortran

 Reporter:  rhaas   |       Owner:  eschnett
     Type:  defect  |      Status:  new     
 Priority:  major   |   Milestone:          
Component:  Carpet  |     Version:          
 Keywords:          |  
--------------------+-------------------------------------------------------
 I get the following error messages (the second commit changes
 make.code.defn to activate code from the first commit):
 {{{
  In file
 /home/rhaas/ET/configs/et/build/Carpet/LoadBalanceReal/carpet_region.f90:59

       type(superregion2), pointer, intent(out) :: sregion
                                 1
 Error: POINTER attribute conflicts with INTENT attribute at (1)
 }}}

 this happens with gfortran 4.2 on a red hat 5.7 system (eg. the cct
 machines or my workstation at Caltech or (former workstation at) GT). I
 attach the full make output (with many more errors).

 Looking at the fortran code it states that:
 {{{
   ! Note that using intent on pointer arguments requires fortran 2003.
   ! It is not allowed in fortran 90 or 95.
 }}}
 I tried setting std=f2003 in gfortran (see make.log) but apparently this
 is not sufficient for gfortran 4.1.2

 I am not which other fortran compilers are affected. If we keep this then
 we will have to make very clear all user realise that Carpet requires
 Fortran 2003 and a fairly new gfortran compiler (or intel) not just
 Fortran 90.
