State-Changed-Why:
    2001-06-12  Nathan Sidwell  <nathan@codesourcery.com>
    
    	PR c++/3130, c++/3131, c++/3132
    	* cp-tree.h (BINFO_UNSHARED_MARKED): New #define.
    	* class.c (force_canonical_binfo_r): Move
    	BINFO_UNSHARED_MARKED, BINFO_LOST_PRIMARY_P. Don't move
    	virtual bases unless they're primary and what they're primary
    	too has been moved.
    	(dfs_unshared_virtual_bases): Use BINFO_UNSHARED_MARKED. Cope
    	with morally virtual bases. Duplicate BINFO_LOST_PRIMARY_P and
    	BINFO_PRIMARY_BASE_OF. Clear BINFO_VTABLE for all but the most
    	derived binfo.
    	(mark_primary_bases): Use BINFO_UNSHARED_MARKED.
    	(layout_nonempty_base_or_field): Add most derived type
    	parameter. Adjust.
    	(layout_empty_base): Likewise.
    	(build_base_field): Likewise.
    	(build_base_fields): Likewise.
    	(propagate_binfo_offsets): Add most derived type
    	parameter. Skip non canonical virtual bases too.
    	(dfs_set_offset_for_unshared_vbases): Don't skip primary
    	bases. Do skip canonical bases.
    	(layout_virtual_bases): Adjust.
    	(layout_class_type): Adjust.
    	(dfs_get_primary_binfo): Build list of virtual primary base
    	candidates.
    	(get_primary_binfo): Check that the shared virtual primary
    	base candidate was found first.
    	(accumulate_vtbl_inits): Don't do anything for non-vptr
    	containing binfos. For case 1 primary virtual bases, keep
    	checking that we've not emerged from the hierarchy of RTTI_BINFO.

    	* g++.old-deja/g++.abi/vbase5.C: New test.
