Ulrich Drepper a1d84548c8 Update.
2000-02-11  Ulrich Drepper  <drepper@redhat.com>

	* stdio-common/printf-parse.h (parse_one_spec): Set wide elements.

	* stdio-common/printf_fp.c: Truely support wide characater output.
	Finally handle decimal points and thousands separator characters
	correctly for multibyte output.
	* stdio-common/printf_size.c: Likewise.
	* sysdeps/generic/printf_fphex.c: Likewise.
	* sysdeps/ieee754/ldbl-96/printf_fphex.c: Likewise.

	* stdio-common/vfscanf.c: Implement I modifier for numbers to read
	locale dependent digits.

	* locale/C-monetary.c (_nl_C_LC_MONETARY): Change wide character
	decimal point and thousands separator values to wide characters from
	wide character strings.
	* locale/C-numeric.c (_nl_C_LC_NUMERIC): Likewise.

	* locale/indigitswc.h: Dereference wcdigits array elements.

2000-02-03  Jakub Jelinek  <jakub@redhat.com>

	* stdlib/canonicalize.c (canonicalize): Zero terminate
	path to copy on error.

2000-02-01  Cristian Gafton  <gafton@redhat.com>

	* misc/syslog.c (closelog): Reset LogType to SOCK_DGRAM.

2000-01-31  Philip Blundell  <philb@gnu.org>

	* sysdeps/arm/fpu/fpu_control.h (_FPU_DEFAULT): Set the AC bit.

2000-01-31  Andreas Jaeger  <aj@suse.de>

	* intl/Makefile (generated): msgs.h is generated.

	* localedata/Makefile (generated-dirs): Add de_DE.437.

2000-01-31  Jakub Jelinek  <jakub@redhat.com>

	* config.make.in: Allow default localedir to come from configure.
	* configure.in: Export libc_cv_localedir.
	* sysdeps/unix/sysv/linux/configure.in: For sparc64, put locale
	stuff into $exec_prefix/lib/locale because it can be shared between
	32bit and 64bit libraries.
	* configure: Rebuilt.
	* sysdeps/unix/sysv/linux/configure: Rebuilt.

2000-01-31  Andreas Jaeger  <aj@suse.de>

	* inet/tst-network.c: New file.
	* inet/Makefile (tests): Add tst-network.

	* inet/inet_net.c (inet_network): Don't overwrite memory or allow
	to great last digits.
