# our current toolchain:
# binutils 2.41 + GCC 13.2.0 + Mingw-w64 11.0.1 with UCRT enabled and winpthreads support
# built from source on Ubuntu 22.04, so should work on any similarily up-to-date distro

# key points:
# * Clang + LLD + libc++ instead of GCC + binutils + stdc++
# * Mingw-w64 with UCRT enabled and winpthreads support
# why are we avoiding GCC? -> Thread Local Storage (TLS) is totally broken
