Does anyone have any ideas why some of my variables seem to get
defined two times, first occurance being in sources they
definitely are not in...

I use a .h -file to define the variables (a really stupid vay,
but...), with #ifdefs trying to make sure they won't be defined
again. In .h, there is nothing but variables (and they aren't 
defined extern). I use those variables in various .c -files,
as they are global. Then I have in all .c's that use those
variables 'vars.h' included... 

eg.
in 'main.c': #include "many_others.h"
             #include "gfx.h"
             #include "vars.h"
in 'gfx.c':  #include <some_others.h"
             #include "vars.h"

However, when I try to compile this, compler tells me that some of
(but not all!) the variables in vars.h are previously defined in some 
other .c -file...
