> 2) -ftransform-exceptions 

should catch(X) expand into "else if (false)" rather than just "if (false)?"

That said, I don't think there is a way to do this using the preprocessor
alone. Consider that

    try { foo (); }
    catch (SomeException ex) {
        puts (ex.what ());
    }

will preprocess to:

    try { foo (); }
    if (false) {
        puts (ex.what ());   // <<< ex undefined
    }
