* tree.h: Forward-declare struct realvaluetype.

	(struct tree_real_cst): Point to the REAL_VALUE_TYPE, do not
	contain it.
	(TREE_REAL_CST_PTR): New accessor.
	(TREE_REAL_CST): Update.
	* real.h: Include machmode.h.
	(realvaluetype): Make it struct realvaluetype, not a typedef.
	(build_real): Prototype here.

	* tree.c: Include real.h.
	(build_real): Allocate the REAL_VALUE_TYPE as a separate
	object in GC memory, set TREE_REAL_CST_PTR to point to it.
	(build_real_from_int_cst): Use build_real.
	* ggc-common.c (ggc_mark_trees): Mark TREE_REAL_CST_PTR of a
	REAL_CST.

	* builtins.c, c-common.c, c-lex.c, dwarf2out.c, expr.c,
	fold-const.c, print-tree.c, real.c, cp/mangle.c, cp/tree.c,
	f/bld.c, f/com.c, f/expr.c, f/target.c, java/decl.c,
	java/jcf-parse.c, java/parse.y, java/typeck.c: Include real.h.
	* Makefile.in, cp/Make-lang.in, f/Make-lang.in,
	java/Make-lang.in: Update dependency lists.
