You could also look at dpp. That's worked for most things I tried 
and was written in part to avoid the problem of macros changing 
behaviour at build time.

Example here:

https://run.dlang.io/?compiler=dmd&source=%23include%20<stdio.h>%0Avoid%20main()%20%7B%0A%20%20%20%20printf("Hello%20dpp.");%0A%7D
