Ulrich Drepper 0d01dace55 Update. 
2002-02-28  Jakub Jelinek  <jakub@redhat.com>

	* elf/rtld.c (_rtld_global): Remove .protected.
	(_rtld_local): Strong alias to _rtld_global.
	* elf/Makefile (CFLAGS-.os): Add -D_RTLD_LOCAL if compiling rtld
	only .os object.
	* sysdeps/generic/ldsodefs.h (GL): If SHARED and _RTLD_LOCAL, use
	_rtld_local instead of _rtld_global.
	(_rtld_local): Add hidden extern, possibly in .sdata section.
	* configure.in: Add tests for visibility attribute and .sdata.
	* config.h.in: Add HAVE_VISIBILITY_ATTRIBUTE and HAVE_SDATA_SECTION.
	* sysdeps/alpha/dl-machine.h: Use _rtld_local instead of _rtld_global.
