"invalid version 0 on git_proxy_options" thrown when natives are built from source

Hi, I'm currently trying to make a custom build that uses libssh2 instead of exec for SSH, since I don't want OpenSSH windows to spawn as my program makes requests. I changed this flag, then followed through the rest of the compilation steps both for native binaries and lg2s.

I then tried pulling, not on a proxy, using this code:

var fOptions = new FetchOptions ();
fOptions.Prune = UpdaterMod.settings.pruneOld;

var mOptions = new MergeOptions ();
mOptions.CommitOnSuccess = true;
mOptions.FileConflictStrategy = UpdaterMod.settings.onFileConflict;

var sig = new Signature (new Identity (modName, email), DateTimeOffset.Now);

try {
    string logHolder = "";
    Commands.Fetch (repo, remote.Name, refSpecs, fOptions, logHolder);

    if (logHolder.Length > 0)
        LogMsg (logHolder, LogMode.Warn);
}
catch (Exception e) {
    LogMsg ($"Could not fetch data from remote repo: {e.Message}", LogMode.Error);
    return;
}

Expected behavior

The program should attempt to pull without trying to use a proxy.

Actual behavior

The caught exception contains the message in the title.

Other useful information

This issue persists when the flag is switched back to exec

从报告中的 Windows 构建版本上的 Commands.Fetch 调用（使用 FetchOptions）开始，然后跟踪 native 构建如何处理代理选项和版本验证。使用 custom 和 exec 配置重现 fetch；当不使用代理的 fetch 不再抛出所报告的无效版本异常时，即表示完成。
