bfd/
* libcoff-in.h (xcoff_section_tdata): Update commentary.
* libcoff.h: Regenerate.
* xcofflink.c (xcoff_link_add_symbols): Set the csect of XTY_ER
symbols to bfd_und_section_ptr or bfd_abs_section_ptr, rather than
the previous symbol's csect. Treat last_symndx as an inclusive value
and simplify its handling.
(xcoff_mark): Treat last_symndx as an inclusive value. Only mark
symbols with the right csect. Don't mark rsec when processing
relocations against undefined or absolute sections.
(bfd_xcoff_size_dynamic_sections): Don't check the SEC_MARK flag
of bfd_und_section_ptr.
(xcoff_link_input_bfd): Likewise.
