同一包中的功能可见性

Question

If I understand correctly - all the source files of a package live at the same scope.

I have two files - room.go:

package main

func newRoom() *room {
    return &room{
        forward: make(chan []byte),
        join:    make(chan *client),
        leave:   make(chan *client),
        clients: make(map[*client]bool),
        tracer:  trace.Off(),
    }
}

main.go:

package main

func main() {    
    r := newRoom()

When I am compiling the code I get the error:

.\main.go:34: undefined: newRoom

Why ?

go run *.go will work in unix like system, and in Windows try to list all files in main package
