GCC/C++ won't let you overload a method name if one method is virtual and the other not.

Update: Some code:

#define g f class A { public: virtual void g(int) = 0; void f() { g(1); } }; class B : public A { void g(int) {} }; int main() { B b; b.f(); return 0; }
This code fails in the compiler:

In function `int main()': 14: error: no matching function for call to `B::f()' 8: note: candidates are: virtual void B::f(int)
If I remove the #define, then it passes the compiler (but fails the linker with vtable issues).

Update 2: As ashley_y points out, the virtual is a red herring, and my issue is with a curious restriction on overloading in C++, so I can't really blame GCC.
