I think in the long run, the goal should be to provide a compiler supporting all C++11 features by default. For purposes of std::thread & co., the choice of distributing an additional pthreads layer library, or writing additional Windows-based functionality for libstdc++, is of course up to you, Kai, and other GCC developers. My preference, as always, is to minimize the number of additional libraries GCC's developer-users are required to redistribute. However, it seems fairly trivial to me to link winpthreads into the libstdc++ DLL, and I would recommend that as a reasonable default action. In the vein of static linkage, however, I do have one observation and a related question. The pthreads-w32 library has startup code that is executed when the DLL is attached, and therefore when the library is statically linked, the user must call startup and shutdown functions. Does winpthreads have the same requirement?
