Right.  If fflush is passed a single stream, and it's a read-only
stream (like stdin), issue a warning (once!  Set a flag to prevent
multiple warnings).

Note: I tried adding this, but there's a lot of places in libc where
we blindly call fflush() on streams (rewind is one), so if we do put
in a warning we'll have to be extra careful about other calls to
fflush, or provide a _fflush that doesn't check for read-only streams.
