Revamped framework search path handling for MacOSX. This should allow two framework builds (in /Library and /System/Library) to coexist with distutils linking against the right one. Should be backported to 2.3, but getting Apple-supplied Python to pick up these fixes is going to be non-trivial.

	double yx;

	y = fabs(y);

		x = y;
		y = temp;

		return 0.;
	else {
		yx = y/x;
		return x*sqrt(1.+yx*yx);
