I received lots of explanations and good advice.  Thanks to:

   TW = "Tracy J. Di Marco White" <gendalia@iastate.edu>
   TL = Ted Lemon <mellon@hoffman.vix.com>
   MH = "Michael L. Hitch" <mhitch@lightning.oscs.montana.edu>
   JS = Jonathan Stone <jonathan@DSG.Stanford.EDU>:


Here some particularly helpful extracts from the conversation:

I think I can manage to change the Makefile by myself :-), but I must
admit that I have little experience with assembly language, none
recent, and none at all for the MIPS chip. (6502, anyone?)  Could you
post your diffs or explain where I should add ".abicalls"?


(BTW, I eventually got a clean compile on a stock NetBSD 1.2 system,
without libwrap, but I'd like to do this "right", and maybe learn a
thing or two in the process.)
