No he doesn't. The problem is that flex generates C(++) code targeted
mainly for the GNU compiler, which doesn't have an STL iostream yet
(well, not in the official distribution anyway). Microsoft does have this.
A solution might be to include iostream at the top of your flex input file,
and possibly adding
  typedef basic_iostream<char,struct std::char_traits<char> > iostream;
there as well.

If, as John suspects, M$VC also has an iostream.h defining an iostream
class,
things could get trickier. In that case, you're better off changing the
flex skeleton (by including iostream instead of iostream.h if WIN32
is defined, for example) and recompiling flex.
