srcML does a satisfactory job. But indeed, having a solution based on PetitParser is indeed promising.
Yes, and I don't know what to do, and would like to know if you or someone else have any idea of how to solve it. I will think some approach, but if you have some idea to share it would be better so I go directly to a good solution. I'm thinking that to feed the parser I'll have to preprocess the string with another parser, and make a string to string conversion by having a set of defines and paths so that #includes and #ifdefs work. But probably I'll need a cache because the generated string will be huge.

What do you think?

Can't macros and preprocessor directives be represented as just another nodes in the AST?
