Hi,
Here is a patch that adds support for argp argument parsing from
console client plugins. I've also changed the existing plugins to do
so. And as a bonus I've done task #2479: "Generic Speaker Bell Style
Option".
I've also fixed all warnings and changed a function call in ncursesw.
This fixes a small (but not serious) mistake I introduced in a
previous patch.
I've tested this already, and for some magic reason it works even
without Marcus' patch applied. But still I don't advise using it
because argp is not reentrant yet.
There is another small fix to set the current locale. If this is not
done some people could experience some problems with some console
client plugins (Like locale dependent capitalization).
Thanks,
Marco

* bdf.c (bdf_read): Silence a gcc warning by casting the strlen
return value to an int.
* console.c: Include <locale.h>.
(main): Set the locale. Make sure the arguments are parsed in
order. Fix proposed by Göran Weinholt <weinholt@debian.org>.
* driver.c (driver_fini): Change `i' from int to unsigned int to
silence a gcc warning.
(driver_start): Likewise.
(ADD_REMOVE_COMPONENT): Likewise.
(driver_add): Cast the return value of driver_len_list to an int
to silence a gcc warning. Set up argc and argv so it can be used
by argp.
* driver.h (struct driver_ops): Remove the *NEXT argument from
the interface of the member `init'.
* generic-speaker.c: Include <string.h>. Include <argp.h>.
(struct melody): New member `name'. Every melody was given a
name.
(doc): New variable.
(options): Likewise.
(argp): Likewise.
(parse_opt): New function.
(generic_speaker_init): Parse the arguments using argp.
(generic_speaker_play_melody): Use a cast to silence a gcc
warning.
* ncursesw.c: Changed all calls to the function `ncurses_refresh'
to `refresh_screen'.
(input_loop): Change `i' from int to unsigned int to silence a gcc
warning.
(ncursesw_set_cursor_pos): Use a cast to silence a gcc warning.
* vga.c (current_width): Changed type to unsigned int to silence a
gcc warning.
(current_heigh): Likewise.
(struct vga_display): Changed the type of the members `width' and
`height' to unsigned int to silence a gcc warning.
(doc): New variable.
(options): Likewise.
(argp): Likewise.
(parse_opt): New function.
(parse_startup_args): Function removed.
(vga_display_init): Use argp now.
(vga_display_set_cursor_pos): Use a cast to silence a gcc warning.
(vga_display_change_font): Disabled the unused code for now.
