Ошибка компиляции openvpn3 в windows под mingw64 — переменная не была объявлена ​​в области видимости

Я получаю эту ошибку, пытаясь скомпилировать openvpn3 (https://github.com/OpenVPN/openvpn3в окнах под mingw64

Я посмотрел на заголовочный файл, который вызывает ошибку, и tap определяется в параметрах функции

void adapter_config_l2(HANDLE th,
const std::wstring& openvpn_app_path,
const Util::TapNameGuidPair& tap,
const TunBuilderCapture& pull,
ActionList& create,
ActionList& destroy,
std::ostream& os)
{
// Make sure the TAP adapter is set for DHCP
{
const Util::IPAdaptersInfo ai;
if (!ai.is_dhcp_enabled(tap.index))
{
os << "TAP: DHCP is disabled, attempting to enable" << std::endl;
ActionList::Ptr cmds(new ActionList());
cmds->add(new Util::ActionEnableDHCP(tap));
cmds->execute(os);
}
}

// set TAP media status to CONNECTED
Util::tap_set_media_status(th, true);

// ARP
Util::flush_arp(tap.index, os);

// We must do DHCP release/renew in a background thread
// so the foreground can forward the DHCP negotiation packets
// over the tunnel.
l2_thread.reset(new std::thread([this, logwrap=Log::Context::Wrapper(), tap]() {
Log::Context logctx(logwrap);
::Sleep(250);
const Util::InterfaceInfoList ii;
{
std::ostringstream os;
Util::dhcp_release(ii, tap.index, os);
OPENVPN_LOG_STRING(os.str());
}
::Sleep(250);
{
std::ostringstream os;
Util::dhcp_renew(ii, tap.index, os);
OPENVPN_LOG_STRING(os.str());
}
}));
}

Что может быть причиной этой ошибки?

Вот некоторая информация о моей среде сборки:
Windows 10, GCC 7.1.0, msys2 mingw64. я на последнем коммите. мой скрипт сборки выглядит так
