I'm using the Minix standard I/O library on Ms/Dos and the stdout stream
doesn't automatically get flushed on a newline.

There are these perprintf macros/flags that I've never seen on other Unix/C
implementations which flush every fprintf.

But when the application software is using various combinations of
fputs/fputc, seems the output stream won't get flushed unless the program
specifically requests it.  

I've been looking at various reference materials (Harbisan & Steele, DPANS,
K&R 2nd Edition) and I've yet to stumble across anything that defines the
flushing algorithm.  Did I miss it?

I believe accepted practice is to flush when encountering a newline
character or the buffer files up.  So the perprintf stuff may be done away
with and fputc check for newline characters.
