Compiler is hosed.  A workaround is to include this line in your handy-dandy
VC6 workaround header:
inline void operator delete(const void* p) throw() {operator
delete(const_cast<void*>(p));}

It would probably be a good thing to add this bug and workaround to the VC
known bug page, since it does affect significantly affect
Boost.SmartPointer.  Also, to be more complete, one would add similar
workaround lines for deletion of const arrays, plus deletion with
std::nothrow.
