Inside: C:\Program Files\Go\src\syscall\types_windows.go

var signals = [...]string{
    //Omit line n here....
    /**Compatible with Windows start*/
    16: "SIGUSR1",
    17: "SIGUSR2",
    18: "SIGTSTP",
    /**Compatible with windows end*/
}
/**Compatible with Windows start*/
func Kill(...interface{}) {
    return;
}
const (
    SIGUSR1 = Signal(0x10)
    SIGUSR2 = Signal(0x11)
    SIGTSTP = Signal(0x12)
)
/**Compatible with windows end*/

For example on go1.5.1, the C:\Go\src\syscall\types_windows.go file is missing, but
After you edit the C:\Go\src\syscall\ztypes_windows.go file you receive 10 warnings:
dll_windows.go 1 warning in func (p *Proc) Call(...) (...) {...},
exec_windows.go 1 warning in func joinExeDirAndFName(...) (...) {...},
zsyscall_windows.go 8 warnings possible misuse of unsafe.Pointer.
If it is enough to comment out the return keyword in the first two files, then it is not clear how to fix the last one.
Ideas?

fix: rename ztypes_windows.go to types_windows.go
If the fix did not help, then add a new fix file C:\Go\src\crypto\x509\root_windows.go
fix: in function checkChainSSLServerPolicy() , replace the string

	para := &syscall.CertChainPolicyPara{
		// ExtraPolicyPara: uintptr(unsafe.Pointer(sslPara)),
		ExtraPolicyPara: syscall.Pointer((unsafe.Pointer(sslPara))),
	}
