	* elflink.h (elf_merge_symbol): Call elf_backend_copy_indirect_symbol
	to copy any information related to dynamic linking when we flip
	the indirection.

ld/testsuite/

2003-04-28  H.J. Lu <hjl@gnu.org>

	* ld-elfvers/vers.exp (picflag): Set PIC flag for compiler.
	(build_vers_lib): Support PIC.
	(build_vers_lib_no_pic): New. Change all calls to build_vers_lib
	to build_vers_lib_no_pic.
	(build_vers_lib_pic): New.
	Add tests vers26a, vers26b1, vers26b2 and vers26b3 for versioned
	definition vs. normal definition in different files.

	* ld-elfvers/vers26a.c: New file.
	* ld-elfvers/vers26a.dsym: Likewise.
	* ld-elfvers/vers26a.map: Likewise.
	* ld-elfvers/vers26a.ver: Likewise.
	* ld-elfvers/vers26b.c: Likewise.

	* ld-elfvers/vers26b.dsym: New empty file.
