I have three files
main.c===============

include <stdio.h>

include <string.h>

int main()
{
//Decl
char input[81];
int keep_running = 1; //To keep loops running

while( keep_running == 1) //Main Screen
{
printf("-- ");
gets(input);

 if ( strcmp (input, "hi") == 0)
 {
      list();
 }
 if ( strcmp (input, "boo") == 0)
 {
      help();
 }
 else
 {
      printf("Unknown Command\n");
 }

} //while end
} //Main end

Functions.h

ifndef FUNCTIONS_H_INCLUDED

define FUNCTIONS_H_INCLUDED

/ ^^ these are the include guards /

/ Prototypes for the functions /
/ Sums two ints /
//Function Decl
void list();
void help();

endif

Functions.c

include "Functions.h"

void list()
{
printf("FILES LISTED\n");
}
void help()
{
printf("HELP STUFF");
}

And when I try to compile I get error:
cannot find -lobjc
ld returned 1 exit status
C:\Users\bob\Documents\file\Makefile.win [Build Error] [Game.exe] Error 1

How can I fix this?

Just remove objc from the library list..
Project->options->libraries ( or something like that, I don't use dev-c++ any more )
You'll see a -lobjc in the list there, just remove it and everything is fine
