Ulrich Drepper cf29ffbef9 Update.
1997-05-25 03:00  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dynamic-link.h (_dl_verbose): New variable, declare.
	* elf/rtld.c (_dl_verbose): New variable, define.
	(dl_main): Define _dl-verbose based on DL_WARN environment variable.
	* sysdeps/i386/dl-machine.h (elf_machine_rel): Print warning about
	changed size in copy relocation only if symbol in shared object
	is larger or _dl_verbose is nonzero.
	* sysdeps/m68k/dl-machine.h (elf_machine_rel): Likewise.
	* sysdeps/powerpc/dl-machine.h (elf_machine_rel): Likewise.
	* sysdeps/sparc/dl-machine.h (elf_machine_rel): Likewise.

	* nis/nss_nis/nis-ethers.c: Don't use relative include paths, use
	<...>.
	* nis/nss_nis/nis-grp.c: Likewise.
	* nis/nss_nis/nis-hosts.c: Likewise.
	* nis/nss_nis/nis-network.c: Likewise.
	* nis/nss_nis/nis-proto.c: Likewise.
	* nis/nss_nis/nis-pwd.c: Likewise.
	* nis/nss_nis/nis-rpc.c: Likewise.
	* nis/nss_nis/nis-spwd.c: Likewise.
	* sysdeps/unix/sysv/sysd-stdio.c: Likewise.
	* wcsmbs/wcscoll.c: Likewise.
	* wcsmbs/wcstod.c: Likewise.
	* wcsmbs/wcstof.c: Likewise.
	* wcsmbs/wcstol.c: Likewise.
	* wcsmbs/wcstold.c: Likewise.
	* wcsmbs/wcsxfrm.c: Likewise.
	Reported by Zack Weinberg <zack@rabi.phys.columbia.edu>.

	* time/strftime.c: Implement # flag which changes case of output for
	%a, %b, %B, %p, and %Z format.
	When printing numbers, the given field width is always respected.
	This means that padding happens only up to the given width.
	Proposed by Stephen Gildea <gildea@intouchsys.com>.

1997-05-25 00:44  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/i386/fpu/__math.h (logb): Fix thinko, reverse output
	values.
	Reported by Andreas Jaeger <aj@arthur.rhein-neckar.de>.
