Oops... looks like I typed faster than I thought ;-)
I use stock Allegro WIP; like Damian Yerrick pointed out, I meant to
write `destroy_bitmap' instead of `release_bitmap', and
create_bitmap(bitmap, w, h) should have been
bitmap=create_bitmap(w,h).
Sorry if I caused any confusion here.

yeah, sorry... that's an other typo. :-)

Anyway, from what I understand, what you want is something like the
following

BITMAP *realloc_bitmap (BITMAP *bmp, int w, int h)
{
   if (bmp)
      destroy_bitmap (bmp);
   return create_bitmap (w, h);
}

and then do 

bmp=realloc_bitmap(bmp,new_w,new_h);

anyway, I hope my previous post didn't create more confusion than it
aimed to clear up.
