	* gimple.c (gimple_types_compatible_p): Check type qualifications
	before merging pointer to complete and pointer to incomplete type.
	* lto-symtab.c (lto_symtab_resolve_symbols): For commons make sure

	doesn't do the job we want it to do here.

	lto/
	* lto.c (read_cgraph_and_symbols): Do not collect.
