Only partially fixed in DMD 0.176. Stepping up the priority since compiler
behaviour is now inconsistent.

void main() {
        int c;
        c = c << 33; // Error: shift left by 33 exceeds 32
}

void main() {
        int c;
        c = c >> 33; // Works, shouldn't
}

void main() {
        int c;
        c <<= 33; // Works, shouldn't
}

void main() {
        int c;
        c >>= 33; // Works, shouldn't
}

void main() {
        int c;
        c = c >>> 33; // Works, shouldn't
}

void main() {
        int c;
        c >>>= 33; // Works, shouldn't
}

Also, this error message seems a bit strange:

void main() {
        int c;
        c = c << -1; // Error: shift left by -1 exceeds 32
}
