Now when I tried to run 'go build .' with my sftp project on z/OS USS, it failed with error
../../go/pkg/mod/github.com/pkg/sftp@v1.13.6/attrs.go:101:2: undefined: fileStatFromInfoOs
../../go/pkg/mod/github.com/pkg/sftp@v1.13.6/ls_formatting.go:70:24: undefined: lsLinksUIDGID

I am wondering if this sftp package supports IBM mainframe zos/s390x or not? If yes, what could be the reason of the above problem?
If not, what needs to be done to add the support?

Thank you in advance.
