Found this guy in the wild. Win32 related code. Works in MSVC. In a macro. Works fine if you take off the token-pasting, since "" "" is string concat. I think the idea here is MSVC allows token pasting when the left andor right aren't actual tokens, and just continues. So effectively they are ignored.
