 	Hmm, that would be sun2, many vaxen, most every sun3 and
 	hp300, sun4/100, sun4/200, sparc1, acorn26 ... and more

 	Yes, they are uninteresting to most people, but they tend
 	to act as an (insufficient) curb on some of the excesses
 	of bloat.

 	Personally I'd be happy with the compile time option to
 	select fixed offsets, or to go through the extra table,
 	but as I'm not volunteering code you can determine how much
 	weight that option carries :)
