FWIW, the correct specialization gets instantiated and compiled. It is
actually a name mangling problem. With vc6 name mangling the template
arguments are not part of the mangled name. As a result the linker can not
differentiate between foo<int>() and foo<double>(). The usual workaround is
to do something like this.

template <class T>
foo(T* = 0) {}
