// The ordinal DLL contains exactly one function (other than DllMain, that is) with ordinal number
// 1. This function has the sugnature `fn() -> *const c_char` and returns a string "bunny\0" (in
// reference to WindowsBunny).
//
// Both x86_64 and x86 versions of the .dll are functionally the same. Ideally we would compile the
// dlls with well known ordinals from our own testing helpers library, but rustc does not allow
// specifying a custom .def file (https://github.com/rust-lang/rust/issues/35089)
//
// The DLLs were kindly compiled by WindowsBunny (aka. @retep998).
