cp-tree.h (register_dtor_fn): New function. 

* cp-tree.h (register_dtor_fn): New function.
	* decl.c (destroy_local_static): Rename to ...
	(register_dtor_fn): ... this.  Give it external linkage.
	(expand_static_init): Use it.
	* decl2.c (do_static_initialization): Likewise, if using
	__cxa_atexit.
	(do_static_destruction): Check that __cxa_atexit is not in use.
	(finish_file): Don't call do_static_destruction if using
	__cxa_atexit.

	* typeck.c (convert_arguments): Restore two-message error
	reporting.
