Hi!
Normal preprocessing, -fdirectives-only preprocessing before the Nathan's
rewrite, and all other compilers I've tried on godbolt treat even \*/
as end of a block comment, but the new -fdirectives-only handling doesn't.
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux, ok for
trunk?
