Independent of your patch, should we raise this as a gcc bug, that when it does constant-folding optimization of signbit at compile-time (signbit(-0.0) => 1), it results in a different value than when the macro is used on a runtime value (signbit(result) => mask off all but the sign bit)? - -- Don't work too hard, make some time for fun as well!
