Changes from version 1.3 to 1.4

+ Improves compatibility WINDOWS - LINUX - MACOSX

The sentences #include <cdiv.h> become #include "cdiv.h" ie the symbols ( < > are replaced by " ) because these symbols are not recognized by MACOSX.

Is added to the documentation an installation tutorial MACOSX.

+ Disappears change_chanel() function

+ New global variables:

Global variables os_type, midi_pos, midi_time

+ New function and process for joysticks:

SAMPLE * sound_get_sample( int id_snd );
unsigned long sound_get_length( int id_snd );

void sound_pause( int id_canal )
void sound_resume( int id_canal )

int sound_get_position( int id_canal );

unsigned char sound_get_volume( int id_canal );
void sound_set_volume( int id_canal, unsigned char snd_vol );
void sound_ramp_volume( int id_canal, int snd_time, int endvol );
void sound_stop_ramp_volume( int id_canal );

unsigned char sound_get_frequency( int id_canal );
void sound_set_frequency( int id_canal, unsigned char snd_frec );
void sound_sweep_frequency( int id_canal, int snd_time, unsigned char endfreq );
