Actually, the 'problem' is in the C Set++ runtime library routines,
and may not be a problem at all.  I don't know if ANSI covers this
specific situation, but I've run across the same problem on many UNIX
machines as well.  There is a simple solution, though: turn off
buffering for stdout with the setvbuf() function, as in :

  char achBuf[2];
  setvbuf(stdout, achBuf, sizeof(achBuf), _IONBF);

...this will do what you want.  Note that the achBuf array is provided
for mostly portability; some runtime libraries will accept NULL and
some don't.  C Set++ doesn't as far as I know, and if you try then this
call will fail.

Cheers,
Brad
