anonymous structs don't work with gcc-2.95.  The build emits nine

include/linux/mmzone.h:135: warning: unnamed struct/union that defines no instances
include/linux/mmzone.h:147: warning: unnamed struct/union that defines no instances
include/linux/mmzone.h:201: warning: unnamed struct/union that defines no instances
