Browse Source 
* 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.
