    I've encountered a difference between cfront 2.1 and g++ 2.2, and
    can't find anything in the ARM that explains who is right.

    Consider:

	extern "C" const int a;

    Cfront 2.1 will compile this into:

	extern int a; (or extern const int a; with +a1)

    g++ 2.2 gives: "uninitialized const `a'"  (g++ 2.1 does not)

    The code in g++ cites 7.1.6 in the ARM. "Unless explicitly
    declared extern, a const object does not have external linkage
    and must be initialized."

    So g++ wants something like this to be happy:

    	extern "C" extern const int a;

    But cfront doesn't like that at all.

    It looks to me like g++ is wrong on this one.

    extern "C" const int a; 

    is a declaration not a definition (7.4). But

    extern "C" {
    const int a;
    };

    Is a definition, so the error is justified on this, and  cfront 2.1
    does give an error.

    Comments ?
