// g++ 1.37.1 bug 900519_03
// The C++ Reference Manual says (in section 8.4.3) "A reference to a
// volatile T can be initialized with a volatile T or a plain T but not a
// const T. A reference to a const T can be initialized with a const T or
// a plain T or something that can be converted into a plain T, but not a
// volatile T."
// g++ fails to disgnose such errors in most cases.
// keywords: references, initialization, type qualifiers
