	single 32-bit word.
	* parse.y: Call do_pending_inlines unconditionally.
	reinit_parse_for_method is now snarf_method.  fn.defpen is no
	longer necessary.  Remove unnecessary <itype> annotation on
	SCOPE.  Do not refer to end_of_file or struct pending_inline.
	* semantics.c (begin_inline_definitions): Call
	do_pending_inlines unconditionally.

	* lex.c: Remove all code now shared with C front end.
	Initialize cpplib properly if USE_CPPLIB.  Put reserved words
	into the get_identifier table.  Rewrite pragma handling to
	work with the registry.  Move code to save tokens for later
	processing to spew.c.

	* spew.c: Rewrite everything in terms of token streams instead
	of text.  Move routines here from lex.c / input.c as
	appropriate.  GC-mark trees hanging off the pending inlines
	chain.
