~ <type> => <type> for all integer types in D, however
~ <type> => int for small integer types in C.

This is a source of silently different behavior between D and C at least in unsigned integer types.

example:

// test.d
import std.stdio;
void main(){
  ushort x = 0xffff;
  writefln("%08x", ~x+1u);
}


// test.c
#include <stdio.h>
void main(void){
  unsigned short x = 0xffff;
  printf("%08x", ~x+1u);
}
