Suppose that it would be possible to declare which macros are to be
considered defined, which are undefined and which are still undecided.
Wave would use the information on defined or undefined macros and
resolve preprocessor directives using them, but leave undecided macros
There could also be a option to prevent macros matching %pattern% to be

Would that not be enough to allow for fine tuned generation of readable
workaround-free code (or preprocessing source for specific platforms)?
