I believe you're guaranteed that 

    extern char my_global_array[];

will work in any case.  Someone else (Eli?  You're always good at catching my
mistakes) could probably verify this.

The external declaration 

    extern char *my_global_array;

however, definitely will _not_ work.  Pointers and arrays are similar, but
they are not the same thing, particularly when defined globally.
