When using the Win32 threading model with the MinGW-w64 toolchain, some users encounter difficulties accessing std::thread. This issue stems from a misunderstanding of the toolchain's threading capabilities.
MinGW-w64 vs. POSIX Threading
While the POSIX threading model is supported out of the box in MinGW-w64, the Win32 model requires additional configuration. GCC does not provide native thread support, relying instead on gthreads or pthreads in glibc for threading. However, MinGW-w64 does not include a port of glibc.

To use std::thread with the Win32 threading model, users have two options:
