I think this is new in glibc 2.10, for the reasons given by Jason Merrill above.
I've discussed this problem with Jerry Quinn before, and he had a
tentative patch that worked for me.
As I understand things, this patch is on hold waiting for a solution
to the bootstrap comparison problem being discussed in another thread.

I am waiting for a solution to these problems to continue work on the
std::sort gcc-in-cxx subproject; keeping all these patches up to date
with trunk is too difficult for me right now.
Currently, I have a patch to an old revision of the trunk.
