strtod() didn't support NAN(...), whose code I meant to borrow for
nan(), so I'm being lazy and just disregarding the argument of nan()
and nanf().  I doubt anyone cares.  The macro adaptors in
linux/cmath/math_private.h already did it and nobody seemed to care,
so...  Approved by Jeff Johnston, I'm checking this in:
