* blockframe.c (inside_main_func): Cleanup slightly. Move

Browse Source 
mainsym def into the block it's used in.
	* configure.in configure:  Allow NATDEPFILES to be recognized in
	.mh files regardless of whitespace.

	* cpu32bug-rom.c (cpu32bug_cmds):  Change load_response string to
	keep downloads from hanging.

	* remote-wiggler.c:  Add support for flash upgrades.
	* (wiggler_error):  Fix message format.  Add new error code.
	* (wiggler_write_byets):  Error code is hex.  Report errors with
	proper routine name.
	* (wiggler_read_byets):  Report errors with proper routine name.
	* (get_packet):  Add support for new flash commands.
	* (wiggler_load):  Call clear_symtab_users() to reset things
	properly after download.
	* (flash_xfer_memory bdm_update_flash_command):  New funxtions to
	support flash upgrades for Wiggler.
	* (_initialize_remote_wiggler):  Add `bdm update-flash' command.
