        * except.h (struct eh_entry): Add false_label field.
        (end_catch_handler): Add prototype.
        * except.c (push_eh_entry): Set false_label field to NULL_RTX.
        (start_catch_handler): When using old style exceptions, issue
        runtime typematch code before continuing with the handler.
        (end_catch_handler): New function, generates label after handler
        if needed by older style exceptions.
        (expand_start_all_catch): No need to check for new style exceptions.
        (output_exception_table_entry): Only output the first handler label
        for old style exceptions.
        * libgcc2.c (__eh_rtime_match): New routine to lump runtime matching
        mechanism into one function, if a runtime matcher is provided.

        (process_start_catch_block_old): Deleted.
        (process_start_catch_block): Add call to start_decl_1().
        (expand_end_catch_block): Add call to end_catch_handler().
