your problem is that you havce more than one .c (or .cpp) file
including your .h files. each will be declaring them. if they
are declared static, then each will have their own copies.
you must pick a file in which to declare your globals -- one
and one only.
try this:
xyzzy.h:
extern int global;
xyzzy.c:
#include "xyzzy.h"
// declare globals for module "xyzzy"
int global=3;
plugh.c:
#include xyzzy.h
// we can use "global" here...
