	* config/mips/tm-mips.h (STORE_STRUCT_RETURN):  Define as noop as
	the pushing of the struct return address is already handled in
	mips_push_arguments.
	* mips-tdep.c (reinit_frame_cache_sfunc):  Fix typo in prototype
	declaration.
	* mipsread.c (parse_symbol, parse_type, upgrade_type):  Add more
	sanity checks for corrupt symbol entries to avoid core dumps
	reported by benson@odi.com. Obviously Ultrix 4.3A cc now has
	the same problems as the OSF/1 alpha cc.
	* mipsread.c (parse_lines):  Iterate over the range of the compressed
	line number entries, the old iteration sometimes failed to stop
	and wrote past the end of the LINETABLE. Add sanity check to avoid
	the same problem in case the line number info is corrupt.
	* mipsread.c (parse_procedure):  Adjust pdr for alpha __sigtramp.
	* mipsread.c (parse_external, parse_partial_symbols):  Ignore stNil
	symbols that are produced for statics in .o files and stLocal symbols
	that are produced for every section in OSF/1 dynamically linked
	 executables.
	* mipsread.c (psymtab_to_symtab_1):  Put out `undefined symbols'
	warning only under `verbose on' as there are many undefined symbols
	in a dynamically linked executable.
