Tue Dec  3 08:38:15 1996  Richard Henderson  <rth@tamu.edu>

	* sysdeps/unix/alpha/sysdep.S: Remove definition of __errno_location.
	Reformat copyright.

	* elf/rtld.c (_dl_start): Don't dereference the value returned by
	elf_machine_got to get _DYNAMIC, instead call new function
	elf_machine_dynamic.
	* sysdeps/alpha/dl-machine.h: Permute elf_machine_got to
	elf_machine_dynamic.  Reformat copyright.
	* sysdeps/i386/dl-machine.h: Likewise.
	* sysdeps/m68k/dl-machine.h: Likewise.
	* sysdeps/mips/dl-machine.h: Likewise.
	* sysdeps/sparc/dl-machine.h: Likewise.
	* sysdeps/stub/dl-machine.h: Likewise.

Tue Oct 15 23:46:00 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* MakeTAGS (sysdep_dirs): Include add-on sysdep directories.

Tue Dec  3 02:06:18 1996  Ulrich Drepper  <drepper@cygnus.com>

	* Makerules ($(libdir)/libc.so): Make first line of generated
	link script contain `/* GNU ld script'.  This will be used in
	ldconfig to check for linker scripts.
	* sysdeps/mach/hurd/libc-ldscript: Likewise.
	* sysdeps/mach/hurd/libc_p-ldscript: Likewise.

	* stdlib/getsubopt.c: Update copyright.  Correct typo in comment.
