As pointed out, it is the macros that are the source of most problems, but I write my own parser to handle code with conditional compilation and if I didn't need to do that I would be much happier.</div><div><br></div><div>That could be handled, I think, by trimming the code after it has been parsed. That is, let the parser understand about -ifdef, -if and friends and build a corresponding parse tree that is pruned before being sent to the compiler. Unfortunately, I can't see any good way to make that backwards compatible - tools can't just ignore the new tree nodes, so I will most probably have to accept having to reimplement the preprocessor's job myself. </div><div><br></div><div>I don't see this as a negative point for the EEP, but for the preprocessor in general, and I felt I had to get it off my chest :-)</div><div><br></div><div>regards,<br></div><div>Vlad</div><div><br></div></div></div></div>
