There are several header directories, and it would be impractical to feed the directory every time I switch from one module to another. The macro must find the path automatically by doing some sort of "search & replace" on the full pathname (e.g. */src/* -> */inc/*) . I'm sorry, but I'm really bad at e-lisp, otherwise I would have changed your macro somehow to make it work for me...
