[Bug c++/14132] static template member definition fails

Thanks, your reply has shown me what the correct solution is. Your solution is
not enough when there is more than one .o file. Indeed, this "template<class T>
def" syntax only defines classes when GCC sees the static member being accessed
in the current translation unit. So when the old code looks like:

  int A<void>::a;

it must be replaced by:

  template class A<void>;
  template<class T> int A<T>::a;

Since the compiler puts these variables in the "common" section, the linker
won't complain when there are duplicates (since "template<class T> def" will
unfortunately catch all uses of the static members).

Thanks.
