Hi Andrew,

Thanks for tackling this...

I noticed several constructs like

+int feclearexcept(int __excepts)
+{
+
+	if (_libc_arm_fpu_present)
+		__vfp_feclearexcept(__excepts);
+	__softfp_feclearexcept(__excepts);
+
+	return (0);
+}

where you do the softfp thing unconditionally. Why is that, and is it =
intentional?
