Re : Multiply defined symbols.

Under most linkers there are four main causes :
        Using the same object file twice.
        Linking using a lib ,and one of its component objects.
        Undocumented names in vendor supplied libraries.
        
I think however, that you've got problems with your include files.
If you're making any sort of definition that reserves space in a header
file, then you can end up with duplicate names.

IE:
MyHead.h

int x=0;

UseFile1.c

#include <MyHead.h>

UseFile2.c
#include <MyHead.h>

This will cause 'x' to be defined once.

The header file should be changed to :

extern int x;

You shuld then create a file :
manifest.c
with
int x=6;


This also applies to pointers, ie
char * q;
This reserves space as well (the pointer itself, not what it points to)

Some linkers also resent
char * Msg = "John Major is cool";
