The current IDENTIFIER_NODE handling in pp_c_type_specifier can't work because the first thing pp_c_tree_decl_identifier does is assert that the passed tree is a DECL. Instead the following patch arranges us to use pp_c_identifier to dump an IDENTIFIER_NODE.
This (obvious?) patch is required to give a name to sizetype in the middle-end. I'll bootstrap/test it with some other changes, the gcc.dg testsuite is now clean with sizetype having a IDENTIFIER_NODE TYPE_NAME. Ok for trunk?
