State-Changed-By: nathan
State-Changed-When: Sun Sep 15 11:31:31 2002
State-Changed-Why:
    confirmed. I suspect it is because we don't instantiate
    template members in declaration order.

it simply didn't compile with the error message (2.95.2 and 2.95.4 neither):

------------------------------------------------

The SGI 7.3 and the Sun C++ 5.1 work all right and I can't see any illigal
stuff done there.

I just include the source.
>How-To-Repeat:
	
# 1 "s.cc"
template <class T>
class Conversion
{
        public:
                static T MakeT();
                enum { exists = sizeof(MakeT()) };
};

int main()
{
        int i = Conversion<double>::exists;
}
