For a very general case, quite hard, but we do not need it.

If we stick to a few reasonable cosmetic conventions on the affected
blocks (at a guess: correct indentation of the braces, balanced
parentheses in the condition; we want to do that anyway), then it should
be quite easy to write a preprocessor like that.

I do not know how to integrate that in the build system, though. That is
the annoying part IMHO.
