Oops.  Actually, that was the old nan.h.  I see now that the new one does

#define isnan _isnan

in the bare windows case and this is obviously needed for example 21.

To make our life a bit simpler I have just made the additional change of
replacing

#include "nan.h"

by

#if defined(_WIN32) && defined(_MSC_VER)
#define isnan _isnan
#endif

in x21c.c.

Then we don't have to worry about adding the extra -I option to find nan.h
in the build tree, and we don't have to install nan.h so that the installed
examples work.

Please test that my change works for you.  In particular I wasn't sure
whether

#include <float.h>
#include <ymath.h>

were needed or not to determine _isnan. Please put them in if they are
needed.
