    Compiling the following file:

----------
class A {
public:
    A();

    int y;
    char c;
};


class B {
public:
    B();

    char a, b;
};




main(int argc, char **argv)
{
    A a;
    B &b = static_cast<B&>(a);
}


----------

  with the command line:

g++ -c test.cc   

  for gcc 2.7.2 on platform alpha-dec-osf3.2:

$ g++ -v 
 gcc -v
Reading specs from /usr/local/gnu/lib/gcc-lib/alpha-dec-osf3.2/2.7.2/specs
gcc version 2.7.2

  does *not* produce any error messages, where I believe that it
  should.  Quoting from Ellis&Stroustrup, _The Annotated C++ Reference
  Manual_, page 414, ANSI/ISO Resolutions section $5.2.4:

static_cast<T>(e) casts e to a T exactly as (T)e would have done
provided there is an implicit conversion from T to the type of e of
an implicit conversion from the type of e to T.  Otherwise,
static_cast<T>(e) is an error.  

  This looks like a bug to me, but I would also welcome someone
  explaining to me why it isn't.  I replaced the static cast with a
  direct assignment, and that produced errors, implying that there is
  at least no implicit conversion from A-->B.

    This problem has also been noted (in a substantantially more
  complicated example) in a gcc 2.7.1 cross compiler from
  alpha->i386.  In that more complicated example, I verified that
  there was also no implict conversion from B-->A.
