How to reduce compiled file size?

Lets compare c and go: Hello_world.c :

#include<stdio.h>
int main(){
    printf("Hello world!");
}

Hello_world.go:

package main
import "fmt"
func main(){
    fmt.Printf("Hello world!")
}

Compile both:

$gcc Hello_world.c -o Hello_c 
$8g Hello_world.go -o Hello_go.8
$8l Hello_go.8 -o Hello_go

and ... what is it?

$ls -ls
... 5,4K 2010-10-05 11:09 Hello_c
... 991K 2010-10-05 11:17 Hello_go

About 1Mb Hello world. Are you kidding me? What I do wrong?

(strip Hello_go -> 893K only)
