Log:
	Partly apply restrict volatile bitfield fix from bernd.
	2010-12-02  Bernd Schmidt  <bernds_cb1@t-online.de>

	* expr.c (store_field): Avoid a direct store if the mode is larger
	than the size of the bit field.
	* stor-layout.c (layout_decl): If flag_strict_volatile_bitfields,
	treat non-volatile bit fields like volatile ones.

testsuite:

	* g++.dg/abi/bitfield12.C: Add option -fno-strict-volatile-bitfields.
