can't use go build, show too many errors

[2311586094]

if your work use this file, when you go build to make a exe, there will be

undefined: syscall.SIGUSR1
undefined: syscall.SIGUSR2
undefined: syscall.SIGTSTP
undefined: syscall.SIGUSR1
undefined: syscall.SIGUSR2
undefined: syscall.SIGTSTP
undefined: syscall.SIGUSR1
undefined: syscall.SIGUSR2
undefined: syscall.SIGTSTP
undefined: syscall.Kill
too many errors

Because these constants are not available in Windows，
For normal operation, you can modify the file in GOROOT \ src \ syscall \ types_windows.go
Anyway, these constants are useless under windows

var signals = [...]string{      //It already exists， usually in line 67 of the document
    // Omit some rows

    /** change start */
    16: "SIGUSR1",
    17: "SIGUSR2",
    18: "SIGTSTP",
    /** change end */
}


/** change start */
func Kill(...interface{}) {      //It doesn't exist, you can add it after last change
    return;
}
const (
    SIGUSR1 = Signal(0x10)
    SIGUSR2 = Signal(0x11)
    SIGTSTP = Signal(0x12)
)
/** change end */
