Subject: 	* xcofflink.c: Extensive changes to support linking shared
 objects 	and generating a .loader section. 	* libcoff-in.h (struct
 xcoff_tdata): Add import_file_id field. 	(struct xcoff_section_tdata):
 Add first_symndx, last_symndx, 	and ldrel_count fields. 	*
 libcoff.h: Rebuild. 	* coff-rs6000.c (xcoff_howto_table): Correct reloc
 names. 	* coffcode.h (styp_to_sec_flags): Don't set any flags if
 STYP_PAD 	is set. 	* bfd-in.h (bfd_xcoff_import_symbol): Declare.
 	(bfd_xcoff_export_symbol): Declare. 
 (bfd_xcoff_size_dynamic_sections): Declare. 	* bfd-in2.h: Rebuild.
