  27 Verify that expansion of construction variables whose values are functions
  28 (that return lists that contain Nodes, even) works as expected within
  29 a $CPPPATH list definition.
  30
  31 This used to cause TypeErrors when the _concat expansion tried to
  32 join the Nodes with the strings.
