I am trying to make my first multi-file project with RHIDE but the compiler
is giving me errors which I don't know how to fix.  Essentially I am
following a tutorial I got from the net on "C Libraries and Makefiles" from
DevCentral:  (abbreviated)

/* util.c */
#include "util.h"
int rand_seed=10;

int rand()  {...}
void bubble_sort(int m, int a[]) {...}

/* util.h */
extern int rand();
extern void bubble_sort(int, int[]);

/* main.c */
#include <stdio.h>
#include "util.h"
#define MAX 10
int a[MAX];

void main()
{
   int i;
   for (i=0; i<MAX; i++)
       a[i]=rand();
   bubble_sort(MAX, a);
}

Error Message:
----------------------------------
 Error: util.o: In function `rand':
 util.c(6) Error: multiple definition of `rand'
 o:util.c(6) Error: first defined here
 Error: util.o: In function `bubble_sort':
 util.c(12) Error: multiple definition of `bubble_sort'
 o:util.c(12) Error: first defined here
 Error: util.o(.data+0x0):util.c: multiple definition of `rand_seed'
 Error: util.o(.data+0x0):util.c: first defined here
 There were some errors

I just freshly installed DJGPP with RHIDE 1.47 so all the settings are at
default.  This error is consistent with a larger project that I am working
on.  I've already checked the FAQs and many sites on the web to no avail.
Any help or working project examples would be greatly appreciated.

Thanks,
Tony.
