Proposed resolution (10/01):

Add the indicated wording to the indicated sentence in 9.4 [dcl.init] paragraph 5:

A program that calls for default-initialization or value-initialization of an entity of reference type is ill-formed.

Another glitch in the TC1/core issue 178 definition of value-initialization: it's no longer an error to value-initialize a reference. That makes an example like

typedef struct { int &r; } S;
int main() {
  S();  // Error in C++98, okay in TC1!
}
