        * except.c (verify_library_fn): New function.
        (declare_library_fn): Use it.  Initialize TM even if the non-TM
        library function has been user declared.
        (do_end_catch): Don't set TREE_NOTHROW on error_mark_node.
        (expand_start_catch_block): Don't call initialize_handler_parm
        for error_mark_node.
        (build_throw): Use verify_library_fn.  Initialize TM even if the
        non-TM library function has been user declared.  Don't crash if
        any library fn is error_mark_node.

        * g++.dg/eh/builtin5.C: New test.
        * g++.dg/eh/builtin6.C: New test.

        * g++.dg/parse/crash55.C: Adjust expected diagnostics.

        * eh_cpp.cc (__cxa_throw): Change DEST argument type from
        void * to void (*) (void *).
        (_ITM_cxa_throw): Likewise.
        * libitm.h (_ITM_cxa_throw): Likewise.
        * libitm.texi (_ITM_cxa_throw): Likewise.
