2003-10-24  H.J. Lu  <hongjiu.lu@intel.com>

	* elflink.h (NAME(bfd_elf,size_dynamic_sections)): Look up
	hash table for real symbols.

include/

2003-10-24  H.J. Lu  <hongjiu.lu@intel.com>

	* bfdlink.h (bfd_elf_version_expr): Add "symbol" and remove
	"wildcard".

ld/

2003-10-24  H.J. Lu  <hongjiu.lu@intel.com>

	* ldlang.c (lang_vers_match): Check "symbol" instead of
	"wildcard" and "pattern". Fix a typo.
	(lang_finalize_version_expr_head): Likewise.
	(lang_register_vers_node): Likewise.
	(realsymbol): New function.
	(lang_new_vers_pattern): Set "symbol" and remove "wildcard".

	* ldlex.l (V_IDENTIFIER): Allow '\\'.
