+ * objfiles.h (SECT_OFF_BSS): Don't detect invalid sect_index_bss
+ here, let the users of the macro do it.
+ * symtab.h (ANOFFSET): Detect here if the section index is not
+ initialized.
+ * xcoffread.c (find_targ_sec): Don't treat .bss as special,
+ because some objfiles may not have that section at all.
+ * coffread.c (cs_to_section): Ditto.
+ * elfread.c (elf_symtab_read): Detect an uninitialized index
+ value.
+ (elfstab_offset_sections): The macro ANOFFSET cannot be used as an
+ lvalue anymore.
+ * remote.c (get_offsets, remote_cisco_objfile_relocate): Don't use
+ ANOFFSET as an lvalue.
+ * objfiles.c (objfile_relocate, objfile_relocate): Don't use
+ ANOFFSET as an lvalue.
+ * symfile.c (default_symfile_offsets): Don't use ANOFFSET as an
+ lvalue.

* parse.c (build_parse): don't write off the end of the std_regs
