[AD] Number of joystick buttons

[Omar Cornut <cornut@xxxxxxxxxx>]

Hello,

I have received this e-mail today, from someone using a program I released:

(Quote)
"
Anyway I found a small problem with the windows version, I use a 
Playstation 2 controller adapter to use my
 ps2 pad for emulated games on the pc and noticed that I could not 
correctly assign leftto the left d-pad. I
 checked the properties of my game controller on the control panel and 
noticed that lefton the pad counts
 as button 16, which is the highest button number. Since I can correctly 
assign every other control action
 to the pad, I assume that the emulator just has trouble going past button 
number 15. If you could add support
 for button 16 for direct input that would be awesome!
"

I looked in "allegro/include/allegro/joystick.h" and found:
#define MAX_JOYSTICK_BUTTONS     16

Could this be safely increased?
From what I looked, I think it's ok. But I don't have any 16+ buttons 
joystick to test with.
I'm leaving the modification to someone who knows if there's would be any 
problem increasing the limit.

If the definition is changed, the "name_b" table in 
"allegro/src/win/wjoyhelp.c" also need to be updated
accordingly:
static char *name_b[MAX_JOYSTICK_BUTTONS] = {
   "B1", "B2", "B3", "B4", "B5", "B6", "B7", "B8",
   "B9", "B10", "B11", "B12", "B13", "B14", "B15", "B16"
};

Hope it helps,

Omar Cornut
(Note: I'm using Allegro 4.1.9, but did not find related modifications in 
the recent changelog up to 4.1.11)
