The reason why is that these are features of the C++ programming language,
which you're supposed to learn from some textbook. It's in no way specific
to DJGPP as a compiler, so there'd be little point in DJGPP carrying the
documentation for it.

MSDOS is not multitasking-capable, i.e. *has* no concurrent child
processes, so there's little we could do about that.

fork() alone can't be implemented on DOS.  But the usual combination
of fork() with exec() and wait() for doing a non-concurrent subprocess
is equivalent to a spawn() on DOS. If your Unix source is trying to
run a child process concurrently, you'll have to change it
fundamentally. The DJGPP FAQ has something about this, too, IIRC.
