 Another clang compiler issue in r.terraflow:

 {{{
 /Users/Shared/src/GRASS/svn/dev6-r53518/dist.x86_64-apple-
 darwin11.4.2/include/grass/iostream/empq_impl.h:1360:41: error:
       variable length array of non-POD element type
       'ExtendedEltMergeType<keyvalue<cclabel_type>, int>'
   ExtendedEltMergeType<T,Key> in_objects[arity];
 }}}

 A bit of searching tells me that non-POD variable length arrays are not
 part of the C++ spec, but supported as an extension in some compilers.
 clang does not.
