Standalone C ++ Preprocessor

Question

I am looking for a separate C ++ preprocessor. I will use it with another language, so it makes no sense to run a full-fledged compiler, but this is a very limited script language, so #define and #if and other directives will help me a lot.

For example, I would write a file like this:

#define DEBUG
do some stuff
#ifdef DEBUG
    show a message box or whatever
#endif
do some more stuff

Answer 1

Answer 2

What about the GNU C preprocessor?
