Frankly, I don't remember.  If I saw it, it was a *very* long time
ago, but it's perfectly possible I came up with it myself, although
it was probably not original anyway.

Anyway, instead of this yucky if(0) sequence, I'd probably recommend
the judicious use of gotos, if there isn't some stupid rule that
forbids you from using them while permitting the above :-)
