I still like C and strongly dislike C++(codecs.multimedia.cx)

  int32 a;
  int16 b;
  //...
  b = (int16)a;

  int32 a;
  int32 b;
  //...
  b = (int16)a;

  #define a stdio
  
  #define header <a.h> // five tokens: <, a, ., h, > (otherwise preprocessor wouldn't substitue "a")
  
  #include header // one token after substitution: <stdio.h>
  
  int main() {
      struct {
          int h;
      } stdio;
      a.h = 0;
      printf("%d\n", stdio.h);
  }

  #define CMPS x /*
                    */ <y>
  
  #define ALMOST_SHIFT<CMPS
  
  #define FWD_FST(x, y) x
  
  #define CONCAT(x, y) x ## y
  
  #define x
  # /*
       LOL
       */ define y stdio.h
  
  #include CMPS
  
  #undef x
  #undef y
  
  #include FWD_FST(<stdint.h>, y)
  
  // btw. comma is a valid character in a header name. but this will work anyway,
  // because lexing in C works in mysterious ways
  #include CONCAT(<std,def.h>)
  
  int main() {
      int x = 0;
      int y = 0;
      int z = 0;
      printf("%d\n", CMPS z);
      // printf("%d\n", z<ALMOST_SHIFT); // doesn't compile
      // but the rest works fine...
  }
