FPU in qemu-system-i386 works incorrectly

FPU bug in qemu-system-i386 makes software which use floating point numbers work incorrectly. For instance, the one included in attachment prints out 0 instead of 2147483648. The same code works ok in qemu-system-x86_64.

I have this issue in QEMU 2.3.0 on two different x86 guests (Parabola GNU/Linux-libre and libreCMC).
