This is usually what happens. However, the standard linker that comes with TIGCC
(and is also used for asm programs) doesn't support BSS variables, so it can't
dynamically allocate variables.

As a sidenote, C (I think) doesn't really require the "static" keyword for
global variables, just that they are "initialized" in the code, like this:

 int myVar = 0;
 void _main() {
  myVar++;
 }

I don't know if "static" was defined for global vars though.
