Comment (by dfeuer):

 Fun times. I really thought I'd checked the CPP reasonably well, but this
 is the second failure. The real question is whether these conditionally-
 defined names are used outside the module, or whether they're intended
 only for internal use. If the latter, they just shouldn't be exported at
 all.
