>> Release:        Cactus 4.0.b16
>> Organization:
>> Environment:
>> Description:
> There is a long-standing problem in calling CCTK_Reduce from  
> Fortran: Since this function uses a variable argument list, certain  
> architectures (especially x86_64) do not support calling it from  
> Fortran.
>
> The enclosed patch provides a new routine CCTK_Reduce1 which does  
> not use a variable argument list.  Instead of passing the list of  
> grid function indices as variable arguments, it expects them to be  
> passed in as array.
>
> This new routine will be superceded by the new reduction interface  
> once this becomes available.
>
> See <http://www.cactuscode.org/pipermail/users/2004-September/ 
> 001224.html> for the original bug report and the original  
> suggestion for this patch.
