c++/6273: [2003-01-30] User-defined operator+ and use of enum values in computation of array bounds

[bangerth@dealii.org]

Old Synopsis: [2003-01-20] ICE in tree_low_cst, at tree.c:3471, also an error with gcc 2.95.3
New Synopsis: [2003-01-30] User-defined operator+ and use of enum values in computation of array bounds

State-Changed-Why:
    With recent snapshots, it's not an ICE any more. However,
    when reducing the code to the following
    -----------------------
    template <typename> struct X {
        enum { N = 10 };
        int items[N+1];
    };
    template <typename A, typename B> int operator+(A,B);
    X<int> x;
    ------------------------
    we still get an error:
    test/x> ../../bin/gcc-2003-01-30/bin/c++ -c x.cc
    x.cc:6: error: variable-size type declared outside of any function
    x.cc:6: error: variable-size type declared outside of any function
    
    Apparently, the user-defined template op+ is used to
    determine the array size. I don't know whether this is
    right or wrong...
