What about:

int set_app_icon(void *icon, int icontype, int w, int h, int depth)

where icontype specifies the source as, say, ICON_ALLEGBITMAP or
ICON_WINDOWS, w and h specify the dimentions for those platforms that
require it, and depth specifies the color depth for those platforms that
require it.  This way we can either use Allegro bitmaps or icons stored as
Windows resources, or Mac resources, or whatever the native icon resource is
for a platform...
