   2 ! broadcasting to partitioned workers.

  16 ! It's only with Tcl 8.5 (released in 2007) that "the variable 'varName'
  17 ! passed to 'incr' may be unset, and in that case, it will be set to [...]",
  18 ! so to maintain compatibility with earlier Tcl releases, we manually
  19 ! initialize counter variables:
  20 ! { dg-line l_dummy[variable c_compute 0 c_loop_i 0 c_loop_j 0 c_loop_k 0] }
  21 ! { dg-message "dummy" "" { target iN-VAl-Id } l_dummy } to avoid
  22 ! "WARNING: dg-line var l_dummy defined, but not used".
