Yep, heading there now.  Thanks for looking at this.

PS: For posterity sake - these .defn files are transformed to C by the defn2c.pl script included in the source tree:

--
vom at ice:/tmp/ifupdown$ ./defn2c.pl inet.defn  
#include <stddef.h>
#include "header.h"


#include "archcommon.h"
#include "archlinux.h"


static option_default _loopback_default[] = {
{ NULL, NULL }
};
