This isn't any more portable.  *Any* technique that relies on unclosed
strings depends on the exact implementation of the preprocessor.  And
anything that depends on /**/ disappearing from the middle of (what is
intended to become) a single token depends specifically on the Reiser
preprocessor, found in the Bell compilers and nowhere else.
