  Resolve some compiler errors in ast_sockaddr_is_any().
  
  These errors came up once this function was used from within netsock2.c.
  The errors were like the following:
  
  netsock2.c:393: error: dereferencing pointer ‘({anonymous})’ does break strict-aliasing rules
  
  The usage of a union here avoids this problem.
