It seems to be an -ffast-math -mhard-float but I don't know if is it the right one. I have installed emc on some older pc but right now I would install on my laptop pc for fast "prototype". It is a toshiba a300 intel centrino with P8400 and a pci-e (OXPCIe952) card for the parallel and serial port.
