	* trans-array.c (gfc_conv_array_initializer): Change call to
	gfc_error_now to call to gfc_fatal_error.
	* array.c (count_elements): Whitespace. (extract_element): Whitespace.
	(is_constant_element): Changed name from constant_element.
	(gfc_constant_ac): Only use expand_construuctor for expression
	types of EXPR_ARRAY.  If expression type is EXPR_CONSTANT, no need to
	call gfc_is_constant_expr.
	* expr.c (gfc_reduce_init_expr): Adjust conditionals and delete error
	message.
	* resolve.c (gfc_is_expandable_expr): New function that determiners if
