	* nss/getXXbyYY_r.c (REENTRANT_NAME): Cast FCT in __nss_next call.

	* sysdeps/generic/sbrk.c: Always call __brk (0) to update __curbrk.

	* malloc/malloc-size.c (malloc_usable_size): Renamed from
	malloc_object_allocation_size.
	* malloc/malloc.h: Fix decl.

	* sys/select.h: New file, wrapper header.

	* posix/sys/types.h [__USE_BSD]: Include <sys/select.h>; remove
	fd_set, associated macros, and select decl.

	* sysdeps/posix/isfdtype.c: New file.

Tue Jul  2 23:45:14 1996  Ulrich Drepper  <drepper@cygnus.com>

	The latest Japanese proposal for POSIX locales renames the
	CHARMAP keyword in locale definition files to CHARCONV.
	* locale/programs/ld-ctype.c, locale/programs/locales.h: Rename
        function ctype_is_charmap to ctype_is_charconv.
	* locale/programs/locfile-kw.gperf: Replace charmap keyword with
        charconv.
	* locale/programs/locfile-token.h: Add definition of token
        charconv.
	* locale/programs/locfile.c: Recognize charconv keyword.  Rename
        lables according to this.

	* locale/weight.h (get_weight): Cast constants to prevent
        warnings.

	* stdlib/strtod.c, stdlib/strtol.c, string/strcoll.c,
	string/strxfrm.c: Add some more casts to prevent signed<->unsigned
	warnings.

	New stuff described in P1003.1g.
	* misc/Makefile (headers): Add sys/select.h.
	(routines): Add pselect.
	* misc/sys/select.h: New file.  Declare select functions and
	needed data types and macros.
	* sysdeps/generic/pselect.c: New file.  Add generic implementation
	of pselect() function which uses select().

	* posix/getconf.c: Recognize new variables from P1003.1g.
	* posix/posix1_lim.h: Define _POSIX_FD_SETSIZE, _POSIX_QLIMIT,
	_POSIX_HIWAT, and _POSIX_UIO_MAXIOV.
	* posix/unistd.h: Add description of the P1003.1g variables.
	* sysdeps/generic/confname.h: Define _SC_* values for new
	variables.
	* sysdeps/posix/fpathconf.c (fpathconf): Add handling of
	_PC_SOCK_MAXBUF.
	* sysdeps/stub/fpathconf.c (fpathconf): Ditto.
	* sysdeps/posix/sysconf.c (sysconf): Add handling of new
	P1003.1g variables.
	* sysdeps/stub/sysconf.c (sysconf): Ditto.
	* sysdeps/unix/sysv/linux/posix_opt.h: Define _POSIX_POLL and
	_POSIX_SELECT since Linux has this.

	* socket/Makefile (routines): Add isfdtype.
	* sysdeps/generic/sys/socket.h: Add prototype for isfdtype.
	* sysdeps/stub/isfdtype.c: New file.  Stub implementation of
	isfdtype.

	* wcsmbs/wcrtomb.c (wcrtomb): Fix typo.
