My working workaround is to build with > -D_POSIX_THREAD_SAFE_FUNCTIONS=200112L. that is strange, building main/2.34.0.windows.1 works for me both in a mingw64 shell and the git for windows sdk, and the PR[1] worked as well when applied to 2.34/master that uses a git for windows sdk for building it and that would had failed without it as you reported. what version `pacman -q | grep pthread` of the winpthreads library do you have?, anything else peculiar about your build environment that you could think of? that define and the setting in git-compat-util.h should have equivalent effect in your mingw headers; what does the relevant (almost at the bottom, where the problematic functions are defined) part of /mingw64/x86_64-w64-mingw32/include/time.h say?
