I do not get results like yours.

This C program:

#include <stdio.h>
int main(void)
{
    printf("Hello, World!\n");
    return 0;
}

produces execuatables of:
  74,454 bytes (-O3)
  41,472 bytes (stripped)
  23,976 bytes (upx'ed)

while this C++ program  

#include <iostream>

int main()
{
    std::cout << "Hello, World!\n" << std::endl;
}

produces executables of:
  743,636 bytes (-O2)
  236,544 bytes (stripped)
   86,104 bytes (upx'ed)
