+ * 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.

against undefined symbols if the symbol's XCOFF_WAS_UNDEFINED
flag is set. Assert that all undefined symbols are either
