   It seems to lack all floating point:

   1 ]=> (/ 3.0 1.2)

   ;Hardware trap SIGILL
   ;To continue, call RESTART with an option number:
   ; (RESTART 1) => Return to read-eval-print level 1.

Does that work with the C back end?  If not, it's a separate problem;
if it does, then it may just be an artefact of the vestiges of x87
code I left in x86-64.m4, which I plan to take out soon.  You could
try adding `define(DISABLE_387,1)' to x86-64.m4 to test that
hypothesis.

Also, what operating system is this on?
