    where possible.
    * src/w32fns.c (w32_set_mouse_color): Likewise.
    * src/w16select.c (Fw16_selection_exists_p): Likewise.
    * src/process.c (Fnetwork_lookup_address_info): Likewise.
    * src/cygw32.c (Fcygwin_convert_file_name_to_windows)
    (Fcygwin_convert_file_name_from_windows): Likewise.
