Seems reasonable, so done (I fixed one additional spot you missed).

The bigger picture here is that we do actually endeavor to keep
(most of) our headers C++ clean, but our tool cpluspluscheck misses
these problems because it doesn't try to use these macros.
I wonder whether there is a way to do better.
