Originally, real.o did not drag in anything, as it had to fit into
an independent test harness. That will have to happen again, in order
to test C99 features. Maybe this would be an excuse to do some of that
work, or at least find out why you are having trouble.

supposed to work the same on all computers so you would have to
provide a run-time emulator if your computer was not IEEE. Is that
the specification or was that just political propaganda?
