No big deal, but in cases like these (which I ran into reasonably often
when I was porting Emacs to an older-style runtime checker) I find it
easier just to switch to the __FILC__ style. It's easier to maintain one
line than six, and the __FILC__ style works everywhere and is arguably
clearer anyway.
