Actually, sorry, a grep for "union tree_node" won't find the
definition. It is in tree.h, though. In mainline it starts like this:
union GTY ((ptr_alias (union lang_tree_node),
desc ("tree_node_structure (&%h)"), variable_size)) tree_node {
The stuff inside GTY disappears when the file is passed to the C or C++
compiler. (For more information on GTY see
http://gcc.gnu.org/onlinedocs/gccint/Type-Information.html .)
