* target.h (struct gcc_target): Added ms_bitfield_layout_p.
* target-def.h (TARGET_MS_BITFIELD_LAYOUT_P): New. Added to...
(TARGET_INITIALIZER): this.
* doc/tm.texi (TARGET_MS_BITFIELD_LAYOUT_P): Document.
(BITFIELD_NBYTES_LIMITED): Markup fix.
* tree.h (default_ms_bitfield_layout_p): Declare.
(record_layout_info): Added prev_field.
* tree.c (default_ms_bitfield_layout_p): New fn.
* c-decl.c (finish_struct): Disregard EMPTY_FIELD_BOUNDARY and
PCC_BITFIELD_TYPE_MATTERS for MS bit-field layout.
* stor-layout.c: Include target.h.
(start_record_layout): Initialize prev_field.
(place_field): Handle MS bit-field layout, and disregard
EMPTY_FIELD_BOUNDARY, BITFIELD_NBYTES_LIMITED and
PCC_BITFIELD_TYPE_MATTERS in this case. Update prev_field.
* Makefile.in (stor-layout.o): Adjust dependencies.
