I don't think the new IEEE 754 version specifies the behavior of the fmax/fmin functions due to the way they implemented this change. Do you have a publicly accessible reference? For ISO C, there is a different proposal here: <http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2489.pdf> It preserves the existing behavior of fmax/fmin, as far as I can tell.
