No, this only means libgcc and libstdc++ are built using pthreads instead
of the basic Win32 API implementation present in the code. This is required
to enable C++11 <thread>, <future>, and <mutex> in libstdc++. You may have
to redistribute the winpthreads DLL alongside the libgcc DLL.
I don't know about the other things.
