# This zig_default_flags below is meant to avoid CPU feature impurity in
# Nixpkgs. However, this flagset is "unstable": it is specifically meant to
# be controlled by the upstream development team - being up to that team
# exposing or not that flags to the outside (especially the package manager
# teams).
# Because of this hurdle, @andrewrk from Zig Software Foundation proposed
# some solutions for this issue. Hopefully they will be implemented in
# future releases of Zig. When this happens, this flagset should be
# revisited accordingly.
# Below are some useful links describing the discovery process of this 'bug'
