Problem using 'shared_ptr<T>::operator impl-defined-type()'

With Borland 5.5.1, I'm not having any luck using a shared_ptr in a boolean
context.  The compiler complains that the 'if' condition below contains an
"Illegal structure operation".  Is this a known deficiency with my compiler?

#include <boost/shared_ptr.hpp>

int
main(int argc, char* argv[])
{
  boost::shared_ptr<int> intp;

  if (intp) // error here
    ;

  return 0;
}
