Sorry. That's an extremely bad idea for most cases.
The easiest way is to tell vala to emit the symbols that will then be defined
when compiling the generated C code. That way vala will guard you from name
conflicts and the code will be more readable.
In C, the preprocessor is generally used for two things:
- symbolic constants -- but real constants serve the purpose better and
- generic constructs -- but vala does have generics, so you don't need
those.
Even in C++ you usually avoid the preprocessor for most things, because
preprocessor symbols cannot be scoped. Which is doubly so applicable to vala.
