This one is more vicious:

   deprecated_flag:

	TREE_DEPRECATED in
	   ..._DECL

	IDENTIFIER_TRANSPARENT_ALIAS in
	   IDENTIFIER_NODE

tree-ssa-propagate.c:/* Use the TREE_DEPRECATED bitflag to mark statements 
that have been
tree-ssa-propagate.c:#define STMT_IN_SSA_EDGE_WORKLIST(T)       
TREE_DEPRECATED(T)
