        extract_unsigned_integer and friends, not SWAP_TARGET_AND_HOST.
        * defs.h, findvar.c: Move SWAP_TARGET_AND_HOST back to findvar.c.
        Rename it to SWAP_FLOATING to make it clear it is no longer for

        Call error if too few arguments.
        If REG_STRUCT_HAS_ADDR (structs passed by invisible reference),

        Also, make sure structs allocated for return values and invisible
        reference don't violate STACK_ALIGN.

        * valops.c (value_cast):  If a cast like (TYPE[])VALUE (i.e. array
        of unknown length) use sizeof(VALUE)/sizeof(TYPE) as the length.
        * c-typeprint.c (c_type_print_varspec_suffix):  If array length
        is 0, print it, but not if upper_bound is BOUND_CANNOT_BE_DETERMINED.

        * annotate.c, breakpoint.c, defs.h, top.c:  Replace
        enable/disable_breakpoint_hook with modify_breakpoint_hook.
start-sanitize-gdbtk
        * gdbtk.c: Ditto.
        * gdbtk.c: General cleanups, get rid of unused variables.  Redo
        handling of stdout/stderr to just return output as the result of
        the tcl command that caused the output.  Cleanup -Wall stuff.
        * (breakpoint_notify):  Now returns just action and breakpoint
        number.
        * (gdb_get_breakpoint_list):  New routine.  Does the obvious.
        * (gdb_get_breakpoint_info):  Mostly derived from the old
        breakpoint_notify, but returns lots more info.
        * (dsprintf_append_element):  Helper routine, works like printf,
        but appends a tcl element onto the specified DString.  Good for
        building up lists as return values.

        * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
        anymore.  It's not needed (in fact, this routine may not be needed
        anymore).
        * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
        notification protocol.
        * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
        catches.
        * (interactive_cmd):  Use this wrapper around button invocations
        of many commands.  This will catch errors and put the results into
        the command window.  It also updates all the other windows.
        * Also, change reliefs of most things to sunken.  This actually
        looks better.
        * (create_file_win):  Fix margin binding to allow breakpoints to
        work again.
        * (create_asm_win):  Use return value of gdb_disassemble instead
        of implicit I/O to the command window.  
        * (create_command_window):  Use new result protocol to get output
        from commands.

        * (sparclite_ops):  Switch to download_stratum.
        * target.h (enum strata):  Move download_stratum before
        process_stratum so that executable targets get pushed on top of

        problems with those changes were (a) the file didn't compile, (b)
        they changed memset to bzero--memset is correct, (c) they took out
        code to deal with boards lacking floating point, (d) who knows
        what I didn't discover in a quick read.

        c_style_arrays is false (and index is in range).
