You can actually easily (compared to some time ago) write your own language to do that via the power of LLVM. You'll also be able to produce object files that can be linked in C/C++ programs, if you wish. Edit: Or, you know, write a different macro preprocessor for C++. There's nothing special about the standard CPP other than coming bundled with the compiler.
