Trivial reduction.  Produces the same assembly code.
I have yet to see if this contains a problem.
There may be problems with divmod library routines.

int
main (void)
{
  unsigned char t1;
  t1 = 2;
  t1 = (t1 + 40) % 30;

  __asm__ __volatile__ ("out %1,%0": :
			"r" ((unsigned char) 0xff),
			"M" ((unsigned char) 0x17));
  __asm__ __volatile__ ("out %1,%0": :
			"r" ((unsigned char) t1),
			"M" ((unsigned char) 0x18));

  return (0);
}
