oh my bad that's really freaking. Ok I have than to swap to Linux partition.
is there any chance to add support for std::thread ever in GCC at this point?
That's not the right place to ask.
We do not build vompilers just an IDE, that works with many compilers.
We ship with a TDM's gcc on windows to make it easy to start coding for beginners (and most other users) without the need to explicitely download a compiler.
So you as user are free to use any supported compiler, with or without std:thread-support.
