Can I use this technique to expand MACRO(a,b,c,…) into something like F(a,b,c…); G(a,b,c…)?

There you can find a recursive macro expansion implementation (as a gcc hack) that fits on a slide:

  #2""3
  
  #define PRAGMA(...) _Pragma(#__VA_ARGS__)
  #define REVIVE(m) PRAGMA(push_macro(#m))PRAGMA(pop_macro(#m))
  #define DEC(n,...) (__VA_ARGS__)
  #define FX(f,x) REVIVE(FX) f x
  #define HOW_MANY_ARGS(...) REVIVE(HOW_MANY_ARGS) \
      __VA_OPT__(+1 FX(HOW_MANY_ARGS, DEC(__VA_ARGS__)))
  
  int main () {
      printf("%i", HOW_MANY_ARGS(1,2,3,4,5)); // 5
  }

It sounds like the one in the article works for more compilers, but there doesn't seem to be a copy-pasteable example anywhere to check for myself. Also, the "Our GitHub Org" link on the site just links to github.com.
