ben,
	thanks for the insight.  i was able to hack together something
which i believe to do the same thing.. so here is some more openbsd
trivia.  in openbsd, od has been deprecated in favor of hexdump, and
hexdump takes od flags when called as od.. however, it does have the
new gnu od options in hexdump.  so i added this to Makefile instead:

table.s: compdata
        echo '.globl _TRANS_TBL' > table.s
        echo '_TRANS_TBL:' >> table.s
        hexdump -v -e '1/2 ".short 0x%04x\n"' compdata >> table.s

which creates something like:
.globl _TRANS_TBL
_TRANS_TBL:
.short 0xd801
.short 0x0048
.short 0xd8c9
.short 0x0048
.short 0x0000
...

and i was able to make table.o from this.
and i was almost able to fully build... then came link time, and everything
and its brother was undefined.  to make a long story short, i commented out
parts of mapper.h, i changed most of the symbols in x86.S from either having
an underscore or not having an underscore, then i commented out the call to
getopt_long (since i don't have gnu's getopt installed... i will work on
this
later).  after a lot of hacking, i got tuxnes to build. woohoo!

of course, since i'm at work, i haven't actually tried to get it to run
yet..
i will let you know if things work out.

thanks.
