Mon Jul 8 02:14:25 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> cvs/libc-960708
	* libc-symbols.h [GCC >= 2.7] (strong_alias, weak_alias): Use extern
	storage class.  GCC gives an error for non-extern data defns with the
	alias attribute.

Mon Jul  8 00:11:15 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

	* libc-symbols.h (weak_function): New macro.
	For GCC 2.7+ define as __attribute__ ((weak)).
	* elf/dl-minimal.c: Use weak_function as keyword in function defns
 	instead of weak_symbol (NAME) after the defn.
	* stdlib/strtol.c: Likewise.
	* sysdeps/mach/hurd/dl-sysdep.c: Likewise.

	* sysdeps/alpha/dl-machine.h (elf_machine_rela) [RTLD_BOOTSTRAP]:
	If this is defined, don't declare _dl_rtld_map as weak, and
	don't check for MAP pointing to it.  RESOLVE is always null in this
	case, so test with #ifdef instead of if.

	* libc-symbols.h (symbol_set_declare): Use weak_extern instead of
	weak_symbol.
	* csu/initfini.c (_init): Likewise.
	* locale/setlocale.c (DEFINE_CATEGORY): Likewise.
	* misc/efgcvt_r.c: Likewise.
	* sysdeps/alpha/dl-machine.h (elf_machine_rela): Likewise.
	* sysdeps/i386/dl-machine.h (elf_machine_rel): Likewise.

	* libc-symbols.h [ASSEMBLER] (weak_symbol): Macro removed.
	It was not used in any assembler code.
	(weak_symbol_asm): Renamed to weak_extern_asm.
	(weak_extern): New macro replaces weak_symbol for weak extern refs;
	define to weak_extern_asm for [!ASSEMBLER].

	* libc-symbols.h [! ASSEMBLER] [HAVE_WEAK_SYMBOLS] (weak_symbol_asm,
	weak_alias_asm): New macros, renamed from weak_symbol/weak_alias;
	define those now as aliases.
	Change conditional to use __attribute__ syntax for GCC 2.7+, not 2.8+
	[GCC >= 2.7] [HAVE_WEAK_SYMBOLS] (weak_symbol): Do weak_symbol_asm
	after GCC weak attribute decl.
