[boost] Current shared_ptr and MSVC6SP5 is really dangerous

Boosters,

the current implementation of shared_ptr allows the following
program to compile with MSVC6SP5.

#include <boost/shared_ptr.hpp>
boost::shared_ptr<int> p_i;
int main()
{
  p_i = 42;
  return 0;
}

The line p_i = 42; generates no assembly instructions at all, it
is simply ignored.

This is especially dangerous as the compiler belives this to be
the same as p_i = new int(0) which also doesn't generate any
assembly instructions.

I think this is a serious problem and should be addressed.
