	PR fortran/60458
	PR fortran/77296
	* resolve.c (resolve_assoc_var): Deferred character type
	associate names must not receive an integer conatant length.
	* symbol.c (gfc_is_associate_pointer): Deferred character
	length functions also require an associate pointer.
	* trans-decl.c (gfc_get_symbol_decl): Deferred character
	length functions or derived type components require the assoc
	name to have variable string length.
	* trans-stmt.c (trans_associate_var): Set the string length of
	deferred string length associate names. The address expression
	is not needed for allocatable, pointer or dummy targets. Change
	the comment about defered string length targets.
