2003-05-02  Elena Zannoni  <ezannoni@redhat.com>

	* charset.c (GDB_DEFAULT_TARGET_CHARSET,
	GDB_DEFAULT_HOST_CHARSET): Move to earlier in the file.
	(host_charset_name, target_charset_name): New vars for use by
	set/show commands.
	(host_charset_enum, target_charset_enum): New enums for set/show
	commands.
	(set_charset_sfunc, set_host_charset_sfunc,
	set_target_charset_sfunc): New functions.
	(set_host_charset, set_target_charset): Make static.
	(list_charsets, set_host_charset_command,
	set_target_charset_command): Delete functions.
	(show_charset_command): Rewrite as....
	(show_charset): Hook this up with the set/show command mechanism.
	(_initialize_charset): Change names of charsets to match the
	set/show enums. Use host_charset_name and target_charset_name.
	Use set/show mechanism for charset, host-charset, target-charset
	commands. Do not make 'show host-charset' and 'show
	target-charset' be aliases of 'show charset'.

	* charset.h (set_host_charset, set_target_charset): Don't export,
	they are not used outside the file.

gdb/testsuite:
2003-05-01  Elena Zannoni  <ezannoni@redhat.com>

	* gdb.base/charset.exp: Update based on new behavior of set/show
	charset commands.

gdb/doc:
2003-05-02  Elena Zannoni  <ezannoni@redhat.com>

	* gdb.texinfo (Character Sets): Update to reflect new behavior of
	set/show charsets commands.
