        * target.h (to_stopped_data_address): Change prototype to
        take a CORE_ADDR pointer and return an int.
        * target.c (update_current_target): Change to_stopped_data_address
        to match new prototype.
        (debug_to_stopped_data_address): Change appropriately.
        * breakpoint.c (bpstat_stop_status): Change call to
        target_stopped_data_address to use new prototype.
        * frv-tdep.c (frv_have_stopped_data_address): New function.
        (frv_stopped_data_address): Change to new prototype and
        functionality.
        * ia64-linux-nat.c (ia64_stopped_data_address): Change to new
        prototype and functionality.
        (ia64_stopped_by_watchpoint): New function.
        * i386-nat.c (i386_stopped_data_address): Change to new
        prototype and functionality.
        (i386_stopped_by_watchpoint): New function.
        * remote.c (remote_stopped_data_address): Change to new prototype
        and functionality.
        * remote-m32r-sdi.c (m32r_stopped_data_address): Ditto.
        * config/frv/tm-frv.h (frv_stopped_data_address): Change prototype.
        (STOPPED_BY_WATCHPOINT): Change to use frv_have_stopped_data_address.
        * config/i386/nm-i386.h (STOPPED_BY_WATCHPOINT): Change to use
        new i386_stopped_by_watchpoint function.
        (i386_stopped_by_watchpoint): New prototype.
        (i386_stoppped_data_address): Change to new prototype.
        * config/ia64/nm-linux.h (STOPPED_BY_WATCHPOINT): Change to use
        new ia64_stopped_by_watchpoint function.
        (ia64_stopped_by_watchpoint): New prototype.
