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. -- P.
