Update.

1999-06-18  Thorsten Kukuk  <kukuk@suse.de>

	* sysdeps/alpha/atomicity.h: Correct counting of subsections.

1999-06-17  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* stdlib/tst-strtoll.c: Avoid warning about huge constant.

1999-06-20  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* stdio-common/vfprintf.c (group_member): Make parameters and
	return types pointers to CHAR_T instead of UCHAR_T.
	(vfprintf): Change type of work_buffer, workend and string to
	CHAR_T pointer/array.
	(process_arg, process_string_arg): Adjust/remove casts.  Add
	missing use of L_ macro.
	(printf_unknown): Add missing uses of L_ macro.

1999-06-20  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* wcsmbs/wcschrnul.c: Explicitly cast return value to avoid
	warning.

1999-06-20  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* libio/wgenops.c (__wuflow): Fix use of WEOF vs. EOF.  Call
	_IO_switch_to_wget_mode instead of _IO_switch_to_get_mode.
	(__wunderflow): Likewise.
	(_IO_switch_to_wget_mode): Likewise.
	(_IO_init_wmarker): Likewise.

	* libio/wfileops.c (_IO_wfile_seekoff): Call
	_IO_switch_to_wget_mode, not _IO_switch_to_get_mode.
	(_IO_wfile_jumps): Fix pbackfail entry.

	* libio/iosetvbuf.c (_IO_setvbuf): Only call wide char setbuf
	function if the stream is currently unoriented.

1999-06-19  Zack Weinberg  <zack@rabi.columbia.edu>

	* wcsmbs/wchar.h: Define __need___va_list before including stdarg.h.
	Wrap all wide stream functions with #ifdef __USE_ISOC9X.  Use
	__gnuc_va_list in v*w(printf|scanf) prototypes.

1999-06-20  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* libio/oldiopopen.c (_IO_old_proc_open): Apply change from
	1999-03-29 to iopopen also here.
	Reported by Richard Braakman <dark@xs4all.nl>.

1999-06-20  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* include/features.h: Use __GNUC_PREREQ.
	* sysdeps/i386/fpu/bits/mathinline.h: Likewise

1999-06-19  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* stdio-common/vfscanf.c (ungetc, inchar) [COMPILE_WPRINTF]:
	Change EOF to WEOF and remove cast.
	(UNGETC): Remove macro.
	(_IO_vfwscanf): Change isspace to ISSPACE and UNGETC to ungetc.
	* stdio-common/printf-parse.h (find_spec) [!COMPILE_WPRINTF]:
	Change ISASCII to isascii and MBRLEN to mbrlen.
	(parse_one_spec): Compare info.spec always against wchar_t
	values.
	* stdio-common/vfprintf.c: Remove unused ISASCII and MBRLEN.
	(_itoa, _itoa_word) [COMPILE_WRPINTF]: Don't cast second argument.
	(NOT_IN_JUMP_RANGE, CHAR_CLASS): Change (int) to (INT_T), use L_.

1999-06-19  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* libio/Makefile (shared-only-routines): Add oldiofgetpos,
	oldiofgetpos64, oldiofsetpos and oldiofsetpos64.
	(routines): Include oldiofgetpos, oldiofgetpos64, oldiofsetpos and
	oldiofsetpos64 only if doing versioning.
