Comment (by cjones051073):

 I am not sure second guessing the compiler flags used internally during
 the build is the way to go here. Presumably the gcc devs know what they
 sre doing. What would more interest me is why you have this issue, whereas
 all other platforms (including Darwin 9 PPC) do not have any issues..
 Maybe you could try sending a (clean) build log to them to see if they
 have any suggestions as to what is going on.
