Wed May 8 20:04:29 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>

	* Rules (subdir_install): Depend on $(common-objpfx)sor-$(subdir).
	[! libc.so-version]: Clear static-only-routines.
	($(common-objpfx)sor-$(subdir)): New target.
	[static-only-routines]: New static pattern rule for these .so's.
	* Makerules [libc.so-version] ($(slibdir)/libc.so): Target removed.
	[libc.so-version] ($(libdir)/libc.so, $(common-objpfx)libc-syms.so):
	New targets replace it.
	(install) [libc.so-version]: Depend on $(libdir)/libc.so instead of
	$(slibdir)/libc.so.
	* io/Makefile (static-only-routines): New variable.
	* configure.in: Check for tools objdump and objcopy, and for awk.
	* config.make.in (OBJDUMP, OBJCOPY, AWK): New variables.

Thu May  9 01:24:00 1996  Ulrich Drepper  <drepper@cygnus.com>

	* locale/programs/config.h: Remove definition of wint_t.

	* locale/programs/ld-collate.c: Include <wchar.h> instead of
	<wcstr.h>.

	* manual/time.texi: Add some more description for %U and %W
	format of strftime.  Describe new format %V of strftime.

	* resolv/gethnamaddr.c: Prevent warning by preventing variable
	definition.
	* stdio-common/_itoa.c: Ditto.
