I'm not sure I see the problem that you are pointing to. In this program:
int N;
int foobar;
int *bar = &foobar;
int **foo = &bar;
x ()
{
int **x = foo;
return **x;
}
All of 'foobar', 'bar' and 'foo' will be in the list of symbols
referenced by x(). When time comes to emit those symbols,
gimple_referenced_vars(x) will have the set of globals that we are
looking for. Global symbol N will not be in the list, and that's
fine.
