gcc/ChangeLog:
2015-04-27 Trevor Saunders <tbsaunde+gcc@tbsaunde.org>
* defaults.h (PCC_BITFIELD_TYPE_MATTERS): Add default definition
to false.
* dwarf2out.c (field_byte_offset): REmove check if
PCC_BITFIELD_TYPE_MATTERS is defined.
* stor-layout.c (layout_decl): Likewise.
(update_alignment_for_field): Likewise.
(place_field): Likewise.
gcc/cp/ChangeLog:
