We could be mis-communicating: you said "EQ", not 'eq', so I thought
you wanted to supplant the EQ macro on the C level to return non-zero
for two float objects whose values compare equal.  Now it sounds like
you were talking about something entirely different, something that
only matters on the Lisp level.
