When using newer incompatible *.qsf files (e.g. from Quartus 11 or 12) with Quartus 9, a few lines have to be manually deleted. Quartus is telling you which lines are incompatble.
But incompatible example designs hasn't to do with floating point MegaFunctions. They are available in Quartus since long.

Noted. i had tried a simple floating point summation and convert it into integer using megafunction, it's is work. But the problem is i need to round toward positive infinity for my DSP coding but megafunction only support for round to nearest only. Any others way to make it?
