I'm not sure. As you've found, they don't have to be for ELF. I don't
know what the rationale was for making them global; it seems this
knowledge is lost...

Bad things. Anonymous namespaces allow you to put

namespace{
  int dummy;
}

into a header file, and you should get a different variable in each
object file. More importantly, you can do

namespace{
  class Handle{
    Handle(){}
  };
}

in an implementation and expect that it won't clash with somebody
else's Handle class. If the two anonymous namespaces have the same
name, you'll get a clash.
