re PR fortran/37425 (Fortran 2003: GENERIC bindings as operators)

2009-08-30  Daniel Kraft  <d@domob.eu>

	PR fortran/37425
	* dump-parse-tree.c (show_typebound_proc): Renamed from `show_typebound'
	and accept gfc_typebound_proc and name instead of the symtree, needed
	for intrinsic operator output.
	(show_typebound_symtree): New method calling `show_typebound_proc'.
	(show_f2k_derived): Output type-bound operators also.
	(show_symbol): Moved output of `Procedure bindings:' label to
	`show_f2k_derived'.
	* gfortran.texi (Fortran 2003 status): Mention support of
	array-constructors with explicit type specification, type-bound
	procedures/operators, type extension, ABSTRACT types and DEFERRED.
	Link to Fortran 2003 wiki page.
	(Fortran 2008 status): Fix typo.  Link to Fortran 2008 wiki page.
	* gfc-internals.texi (Type-bound Procedures): Document the new
	members/attributes of gfc_expr.value.compcall used for type-bound
	operators.
	(Type-bound Operators): New section documenting their internals.
