This behavior is intended, and it's our best interpretation of table 88,
actually. In postypes.h (new in 3.4) you can find this comment:

    // The standard requires that streamoff can be constructed from
    // instances of fpos using the constructor syntax, but gives no
    // semantics for this construction. In this implementation it
    // extracts the offset stored by the fpos object.
    // Note: In versions of GCC up to and including GCC 3.3, implicit
    // conversion from fpos to streamoff was allowed. This constructor
    // has now been made explicit to improve type safety.
    template<typename _StateT>
      explicit
      streamoff(const fpos<_StateT>&);

Indeed

  std::streamoff off(std::streampos(0));

works.
