If you have to mark the method as abstract, it should produce an error while
compiling, not on linking. I had to figure out the problem because I didn't get
any error when compiling. On big projects have descriptive errors is a must.

//version = WORKS;

interface I {
    void test();
}

abstract class A : I {
    version (WORKS) {
        // Works
        abstract void test();
    } else {
        // Error 42: Symbol Undefined _D2aa1A4testMFZv
        void test();
    }
}

class B : A {
    void test() {
    }
}

int main(string[] args) {
    return 0;
}

A.test can be defined externally in another object file, that's why it's a
linker error.
