Sigh.  Steve is right.  The library's major version number should
have been bumped long ago.  However, if this is the *only* thing
that's broken w.r.t. backwards binary compatibility, I think I can
fix it another way.  I'll see if I can make the isnan() macro
point to the isnan() function when given a double input, and the
isnanf() function when given a float input.
