No, it's because flushing the buffer at the end of each call would make 
`printf' prohibitively expensive, due to the mode-switches from protected 
mode to real mode and back that are required for each call to DOS.

Consider the following snippet:

	for (i = 32; i <= 255; i++)
	  printf ("%c", i);
	printf ("\n");

If DJGPP would flush the buffer for every printf, this would run hundreds 
of times slower than it does today.
