Just to explain why I apporved adding this in the frontend, I don't know if
this matches Jakub's line of reasoning: I figured this comment from tree.h
means that different languages might have different conventions for this, and
therefore this needs to be done in language dependent code.

/* The node that should be placed at the end of a parameter list to
   indicate that the function does not take a variable number of
   arguments.  The TREE_VALUE will be void_type_node and there will be
   no TREE_CHAIN.  Language-independent code should not assume
   anything else about this node.  */
#define void_list_node                  global_trees[TI_VOID_LIST_NODE]
