if I have a file with 3 function in and I only use one how can I compile
the exe so it only includes the code for the functions I call
, do I need certain command line options to GCC

ie. I have the following three files and only want first(),
thanks in advance

testmain.c
--------------------------
#include "test.h"
int main(void){
    first();
    return(0);
}
--------------------------
test.h
--------------------------
void first(void);
void second(void);
void third(void);
--------------------------
test.c
--------------------------
void first(void){
    int x;
    x=0x37;
}
void second(void){
    int x;
    x=0x37;
}
void third(void){
    int x;
    x=0x37;
}
