Description
I work on a project that needs to ship C++ toolchains to users, and I'm excited to try w64devkit as an option. This project also relies heavily on thread-local variables in some situations, which means we have observed dramatic speed differences (in the ballpark of 2x) between winpthreads and other implementations like mcfgthread (or clang-cl using native Windows threading code)
I'm frankly not terribly familiar with the technical details (such as if it is possible to support both winpthreads and mcfgthreads in the same distribution), but there might be more information in issues like this one against msys

Research direction
Start by reading the linked MSYS2 discussion about mcfgthread and comparing its implications with winpthreads in w64devkit's C/C++ toolchain distribution. Determine whether both implementations can be supported and what integration or packaging changes would be required; done means a concrete support plan or a documented feasibility conclusion.
