That's only a warning.  Does the link really fail?

That shouldn't be necessary, at least if those tests are compiled with
`-std=c89'; in C89, `nan' is in the user's namespace, not the
implementation's, and so a user should be allowed to use that name.
If the implementation doesn't handle that case right, then it is a bug.

(Note that nan() is a standard library function that was introduced in
C99.)
