When?  I've never seen this.

Turbo C/ Microsoft C have buffering turned off by default.  DJGPP has
it on.  The above call to setbuf will make DJGPP operate like those
other compilers.  If you are porting a program over to DJGPP it seems
that it would be a lot easier to add one line than to search for every
printf and add a fflush after it.
