sorry for not seeing this sooner.  i stumbled across this dir myself
recently and came to the same conclusions you did (about the non-fpu
stuff).  i pushed some fixes to get it working on my 64-bit desktop.

i haven't tried to integrate the build though.  i was going to let
that wait until we had better overall build integration than add some
more subdir-configure scripts, then should be able to revisit.

ah, very cool.  i saw those includes and thought those were weird but
then gave up on trying to track them down.  i assumed it was some weird
thing that didn't exist anymore.

can you refresh these and see how many are still needed ?  i think the
alu-tst & bits-gen & bits-tst files should be all set now in the latest
tree.  for the fpu-tst, how about we put the details/comments into the
source file itself for now ?
