	When compiling in separate directory put objects into
	subdirectories matching the source layout.
	* Makeconfig (objpfx) [ifdef objdir]: Append $(subdir).
	When looking for configparms try in $(common-objpfx).
	Use $(common-objpfx)SUBDIR to find objects from other subdirectory
	builds.
	* Makerules: Add $(objpfx) to vpath list.
	(make-dummy-dep): Use $(common-objpfx) to avoid creating dummy.d
	more than once.  All uses in dependency lists changed.
	(+make-deps): Make target directory.
	(sed-remove-objpfx): Substitute $(common-objpfx).
	(do-ar, build-extra-lib, $(common-objpfx)stub-$(subdir)): Use
	$(objpfx) instead of $(objdir) for cd command.
	(O%-lib): Always find libc relative to $(..).
	(subdir-stamps): Collect stamp files from subdirs.
	(common-mostlyclean): Remove stub file in $(common-objpfx).
	* MakeTAGS ($P/siglist.pot): Find siglist.c in stdio-common.
	* Rules (dep-dummy-lib): Use $(common-objpfx) to avoid creating to
	more than once.
	($(objpfx)dummy.c, $(objpfx)empty.c): Change target name to use
	$(common-objfpx).  All uses in dependency lists changed.
	(generated): Prepend $(..) to names.
	* bare/Makefile ($(objpfx)lib$(config-vendor).a): Remove $(objpfx)
	from $@.
	* nss/Makefile ($(objpfx)libnss_dns.so, $(objpfx)libnss_db.so):
	Use $(common-objpfx) instead of $(..) in dependencies.
	* sysdeps/mach/Makefile (mach-objpfx): Unconditionally use
	$(common-objpfx) instead of $(..) and (objpfx).
	* sysdeps/mach/hurd/Makefile (hurd-objpfx): Likewise.
	(rpath-link): Likewise.
	(rpcuserlibs): Likewise.
	* sysdeps/unix/Makefile [$(subdir) = stdio-common]: Check for
	errlist.c in $(objpfx), not $(common-objpfx).
	($(common-objpfx)s-proto.d): Special rule not covered by pattern
	rule.
	* sysdeps/unix/make-syscalls.sh: Make syscall rules depending on
	s-proto.d in $(common-objpfx), not $(objpfx).

Thu Aug 29 17:45:49 1996  Ulrich Drepper  <drepper@cygnus.com>

	* nss/nsswitch.c (nss_dlerror_run): Free returned error
	string.

Thu Aug 29 15:53:33 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/libm-ieee754/e_acoshl.c: New file. `long double'
 	implementation.
	* sysdeps/libm-ieee754/e_atanhl.c: Likewise.
	* sysdeps/libm-ieee754/e_remainderl.c: Likewise.
	* sysdeps/libm-ieee754/e_scalbl.c: Likewise.
	* sysdeps/libm-ieee754/s_asinhl.c: Likewise.
	* sysdeps/libm-ieee754/s_cosl.c: Likewise.
