-@item _get_section_contents_in_window
-Set a @samp{bfd_window} to hold the contents of a section. This is
-called from @samp{bfd_get_section_contents_in_window}. The
-@samp{bfd_window} idea never really caught on, and I don't think this is
-ever called. Pretty much all targets implement this as
-@samp{bfd_generic_get_section_contents_in_window}, which uses
-@samp{bfd_get_section_contents} to do the right thing. The
-corresponding field in the target vector is named
-@samp{_bfd_get_section_contents_in_window}.
