This is standard-conforming behavior of fflush(). While I can't, at the
moment, cite a specific reference, the ANSI/ISO standard Does specifically
state that fflush is defined for INPUT streams only. I can, if you need me
to, look it up in the standad and give you the citation. Lemme know.

Therefore, there is no standard-conforming way to flush stdin, and
this behavior on the part of DJGPP is correct (even though not what
you were hoping for!).
