Alternative for isinf (fix for bug 12008) (version 2)

[Francois Gouget]

+#if !defined(HAVE_ISINF) && defined(HAVE_IEEEFP_H)
+#include <ieeefp.h>
+#define isinf(x) (!(finite(x) || isnand(x)))
+#endif

The problem with macros is that something like isinf(*x++) won't do what 
you intend. That's why even for such a simple case a function would be 
better imho.
