    "log"
    "os"
)

func main() {
    _, err := os.Stdin.Stat()
    if err != nil {
        log.Fatalln(err)
    }
}
C:\dev\src\a>go fmt
foo.go
chmod foo.go.662713035: not supported by windows
exit status 2

C:\dev\src\a>

What did you expect to see?

I expect to see no output from gofmt

What did you see instead?

gofmt failed with error message. Chmod is not implemented on Windows, so it is failing.
