decl.c (gnat_to_gnu_entity, [...]): When constructing a ref to variable...

2015-01-06  Olivier Hainque  <hainque@adacore.com>

	* gcc-interface/decl.c (gnat_to_gnu_entity, case E_Variable): When
	constructing a ref to variable, update inner_const_flag from the
	variable TREE_READONLY attribute.
	* gcc-interface/targtyps.c (WIDEST_HARDWARE_FP_SIZE): Remove default
	definition.
	(get_target_float_size): Remove.
	(get_target_double_size): Remove.
	(get_target_long_double_size): Remove.
