I have a trouble with a comparison:

If(1.0>2.0) sometimos return trae. I think it is caused by an hardware
interrupt that modifies copro registers. Tos ave and restore it I use that
code:

	//saving
	asm("fnsave %0\n\t"
    	"fwait\n\t"
	    :"=g" (state87)
    	);

	//Interrupt code.

	//restoring
	asm("frstor %0\n\t"
    	"fwait\n\t"
	    :"=g" (state87)
    	);

But comparison continues wrong sometimos.

Any idea
