Based on patches from Donn Terry <donn@interix.com>:

	* coffcode.h (enum coff_symbol_classification): Define.
	(bfd_coff_backend_data): Rename _bfd_coff_sym_is_global to
	_bfd_coff_classify_symbol.  Change return type.
	(bfd_coff_classify_symbol): Rename from bfd_coff_sym_is_global.
	(coff_slurp_symbol_table): Use coff_classify_symbol.
	(coff_classify_symbol): New static function.
	(coff_sym_is_global): Never define.
	(bfd_coff_std_swap_table): Initialize with coff_classify_symbol.
	* cofflink.c (coff_link_check_ar_symbols): Use
	bfd_coff_classify_symbol rather than bfd_coff_sym_is_global.
	(coff_link_add_symbols): Likewise.
	(_bfd_coff_link_input_bfd): Likewise.
	* coff-sh.c (bfd_coff_small_swap_table): Initialize with
	coff_classify_symbol.
	* libcoff.h: Rebuild.
