While libc++'s support for linux and windows is poor, on Mac OS X it is complete and works great. I am already compiling large c++ programs using a bug-fixed boost, using clang and libc++ on the mac.
So far I have only found one issue in libc++, already fixed, and one issue in clang, which should be fixed soon.
If people want to work on getting libc++ working on linux and windows, that is great. Once they work, the configuration for libc++ in boost might need extending, based on operating system.
