I'd love to be able to start using those too, but last time I checked they are not supported everywhere CMake builds, at least in the standard libraries (see below). > AIX-7.1_IBM-12.1 reports that __IBMCPP_TR1__ must be defined to use TR1. Hopefully, but that would take some investigation. > Xcode 2.1 and 3.2 fail. These builds are not marked as "expected". I'd be okay with dropping these. > This leaves HP-UX.11iv2.ia64-aCC and Solaris-10-8.11_Oracle-12.3. IIUC the Oracle compiler supports C++11 when told to use the proper stdlib. However, I don't think there is a solution on HP-UX with its standard library. > * Explicitly require SP1 for Visual Studio 2008. Okay. For hosting CMake's own build we could even consider requiring VS 2010. One blocker for that on Kitware's side is updating our dashboard machines as needed to be able to host CMake builds even if testing generators for older versions. I'm not sure when I'll have time to do that. > * Disallow compiling in C++98 mode if compiler is capable of C++11. Okay. > * Require TR1 by all means.

We can even remove the config headers for the platforms we don't need to use it, perhaps manually.
