In C, file-scope objects have external linkage.  Is it possible you're
compiling the file as C++?  

I remember from reading the ANSI C rationale that extern was the source of
some difficulty because there was more than one reasonable, well
established practice.  Some linkers want:

        file1.c:        char value[] = "hi";
        file2.c:        extern char value[];

others want:

        file1.c:        extern char value[] = "hi";
        file2.c:        extern char value[];

I chose #1.  You might try #2 (add extern to the definition).  

Funny we haven't bumped into this before.
