	* resolve.c: Static resolving_index_expr initialized.
	(entry_parameter): New function to emit errors for variables
	that are not entry parameters.
	(gfc_resolve_expr): Call entry_parameter, when resolving
	variables, if the namespace has entries and resolving_index_expr
	is set.
	(resolve_charlen): Set resolving_index_expr before the call to
	resolve_index_expr and reset it afterwards.
	(resolve_fl_variable): The same before and after the call to
	is_non_constant_shape_array, which ultimately makes a call to
	gfc_resolve_expr.

	expression must be scalar.
