    Define _GNU_SOURCE to get EAI_NODATA and EAI_ADDRFAMILY
    
    - define _GNU_SOURCE in files where we use EAI_NODATA, to make sure that
      it's declared (#1059730,#1084068,#1109102)

+On a glibc system, EAI_NODATA isn't defined unless _GNU_SOURCE is.  The
+recommended thing is to use AC_USE_SYSTEM_EXTENSIONS to get all extensions
+defined, but that would require fixups in varous other places, so we go for the
+smaller change here.
