hmm i need some more info becuse i had

avision.c: In function 'wait_4_light':
avision.c:2439: error: 'SANE_STATUS_GOODM' undeclared (first use in this 
function)


i had puted this here:

wait_4_light (Avision_Scanner* s)
{
  return SANE_STATUS_GOODM; <<
  Avision_Device* dev = s->hw;

  /* read stuff */
  struct command_read rcmd;
