We'll need to rewrite that function to not use long double, because the goal is to support building it with Mingw.
I can confirm that plopping a minimal version of this routine into one of the tests (so that it compiles with mingw) also produces x87 instructions. I don't think that anything that I did in attachment 65950 would break in mingw (it just adjusts the x87 FPU precision temporarily and then sets it back), but I'll take a stab at figuring out how to do this operation without long double.
