Is the order of static variables at the file level the same within a given translation unit?

Question

I have a program broken into two source files:

example.cpp

#include <iostream>

class A {
 public:
   A(int x) {
      ::std::cout << "In A(" << x << ")\n";
   }
};

static A first(1);
static A second(2);

example__main.cpp

int main(int argc, const char *argv[])
{
   return 0;
}

Is the release of this program a guarantee:

In A(1)
In A(2)

on all platforms and compilers? If so, where in the standard does it say? Does it matter if I use namespaces and firstand secondappear in different namespaces? How about if they are not static and I use an anonymous namespace?
