If you are in truecolour mode, all you need to do is
bitmap = load_bmp(filename, NULL);

If you are in 256-colour mode, you can reduce it to a palettised picture:

get_gfx_mode(...);
set_color_conversion(REDUCE_TO_256);
bitmap = load_bmp(filename, pal);

and then the PALETTE pal contains the modified palette. I think the latest
Allegro WIP also dithers the BITMAP so it looks ok when the colours are
reduced.
