Not to beat a dead horse, but...

A simpler solution. In the ".h" files, NEVER initialize any static globals, instead declare them like:

extern int xxx_abc;
extern int xxx_def[3];
extern int xxx_ghi[20];

Then in the appropriate ".c" file:

   int xxx_abc = 0;
   int xxx_def  = {1,2,3};
   int xxx_ghi  = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19};

void xxx_init()
   xxx_abc = 0;
   xxx_def[0] = 1; xxx_def[1] = 2; xxx_def[2] = 3;
   { int _i; for (_i=0; _i<20; ++_i) xxx_ghi[_i] = _i; }
