* win32-nat.c (display_selector): New function. Displays information about the information returned by GetThreadSelectorEntry API function. (display_selectors): New function. Displays the infomation of the selector given as argument, or of CS, DS ans FS selectors if no argument is given. ( _initialize_inftarg): Add "w32" as info prefix command. Add "info w32 selector" as command calling display_selectors.
