Have you considered to use Nix's gccStdenv? You may try to override it here: https://github.com/wireapp/wire-server/blob/develop/nix/default.nix#L14-L14
E.g.
nginz = pkgs.callPackage ./nginz.nix { stdenv = pkgs.gccStdenv };
This would save us the headache to 💯 ensure that this introduces no regression. 😸
The zauth nginx module uses GCC nested functions, which are not supported by Clang (the default compiler on macOS). Instead of refactoring the C source to remove nested functions, use gccStdenv to ensure GCC is used for the nginz build on Darwin.
