There never was a guaranteed way to do this.  Some people found that
they could exploit a bug in the Reiser preprocessor so they did.  I
don't have a lot of sympathy for them, since when I was faced with
this choice I did it the portable way even though I was using only
Reiser preprocessors at the time.
