#define is a macro feature
change
#define SCREEN_WIDTH unsigned int
to 
#define SCREEN_WIDTH 320
and 
#define SCREEN_HEIGHT
to 
#define SCREEN_HEIGHT 200

Im assuming your using screen mode 13h 320x200
if so change 
: _fmemset(video_buffer,(char)value,SCREEN_WIDTH*SCREEN_HEIGHT+1);
to
_fmemset(video_buffer,(char)value,SCREEN_WIDTH*SCREEN_HEIGHT);

good luck
