(DONT_RELOCATE_SYMFILE_OBJFILE):  Removed.
	* xcoffsolib.h (struct vmap):  Add new members tvma, toffs and dvma,
	remove tadj.
	* exec.c (bfdsec_to_vmap):  Initialize new vmap members, initialize
	tstart and dstart with section VMA.
	* rs6000-nat.c (vmap_symtab):  Relocate relative to the VMA in the
	object file.
	(vmap_ldinfo, xcoff_relocate_core):  Adjust tstart by section offset
	of the text section, remove DONT_RELOCATE_SYMFILE_OBJFILE hack.
	(vmap_exec):  Relocate relative to the VMA in the object file,
	relocate .bss section as well.
	(xcoff_relocate_core):  No longer adjust section addresses by VMA.
	* rs6000-tdep.c (find_toc_address):  Change type of tocbase
	to CORE_ADDR.
	* xcoffread.c (secnum_to_bfd_section):  New routine to get
	BFD section from CS section number.
	(scan_xcoff_symtab):  Make toc_offset section relative.

	* symtab.c (total_number_of_methods):  Avoid core dump if
	baseclass type is still undefined.
