Introduce __isnanf() as an alias for isnanf(), and make the isnan()
macro expand to __isnanf() instead of isnanf() for float arguments. This change is needed because isnanf() isn't declared in strict POSIX or C99 mode. Compatibility note: Apps using isnan(float) that are compiled after this change won't link against an older libm. Reported by: Florian Forster <octo@verplant.org>
