        * Makefile.in: add DLLTOOL = @DLLTOOL@, pass on DLLTOOL to
        sub makes, change clean rule to also remove *.a to remove
        libwigglers.a, in dependencies: add ppc-bdm.o ocd.o ser-ocd.o and
        remove remote-wiggler.o
        * configure.in: add DLLTOOL support
        * configure: regenerate
        * wigglers.def: new file for imports for wigglers.dll
        * ser-ocd.c: new file which is layer between ocd.c and either the
        wigglers.dll or the target box, only stub so far
        * config/powerpc/ppc-eabi.mt: add ppc-bdm.o to TDEPFILES
        * config/powerpc/ppc-sim.mt: add ppc-bdm.o to TDEPFILES
        * config/i386/cygwin32.mh: add ocd.o ser-ocd.o libwigglers.a
        to XDEPFILES, add rules to build libwigglers.a

        checking in changes of Stu Grossman  <grossman@cygnus.com>:
        * remote-wiggler.c: delete
        * ocd.c: new, was remote-wiggler.c
        always include sys/types.h, include ocd.h, move WIGGLER
        commands and many wiggler prototypes to ocd.h, make wiggler_desc
        static, stop making local wiggler functions static,
        define write_mem_command for wiggler_write_bytes
        (wiggler_start_remote): stop hardcoding the target type,
        instead set and use a target_type variable.
        (wiggler_open): add new target_type and ops args
        (wiggler_wait): now no longer takes pid and target_status as args,
        stop trying to set target_status struct, remove BGND insn
        checks
        (read_bdm_registers): renamed to wiggler_read_bdm_registers
        (wiggler_read_bdm_registers): numregs arg changed to reglen arg,
        remove pktlen check, set reglen instead of numregs
        (dump_all_bdm_regs): delete
        (wiggler_fetch_registers): delete
        (wiggler_prepare_to_store): now just an empty function
        (wiggler_store_registers): delete
        (wiggler_read_bdm_register): new
        (wiggler_write_bdm_registers): new
        (wiggler_write_bdm_register): new
        (wiggler_write_bytes): use write_mem_command variable instead of
        WIGGLER_WRITE_MEM
        (get_packet): renamed to wiggler_get_packet, change refs throughout
        (put_packet): renamed to wiggler_put_packet, change refs throughout
        (wiggler_get_packet): add break to default case of switch,
        change length of WIGGLER_GET_VERSION len to 10 from 4 to match
        specs
        (wiggler_mourn): unpush_target with current_ops, not &wiggler_ops
        (flash_xfer_memory): delete
        (noop_store_registers): new placeholder replacement for
        target_store_registers() which prevents generic_load from trying to
        set up the PC.
        (bdm_update_flash_command): add store_registers_tmp variable,
        make handling of wiggler_ops more generic -- define wiggler_ops
        in a target-specific file instead (such as ppc-bdm.c in the case
        of the ppc), use current_target to deal with registers again
        making this file less target-specific.
        (bdm_read_register_command): new
        (_initialize_remote_wiggler): stop doing add_target (&wiggler_ops),
        comment out add_cmd ("read-register", ...)
        * ocd.h: new, contains common wiggler prototypes, command definitions
        * ppc-bdm.c: file for ppc-specific OCD code, including target_ops
        structure for ppc bdm
        (bdm_ppc_open): new
        (bdm_ppc_wait): new
        (bdm_ppc_fetch_registers): new
        (bdm_ppc_store_registers_: new
        (_initialize_bdm_ppc): new
	* config/powerpc/tm-ppc-eabi.h: add necessary CPU32 BDM defines
