 	Initialize `result'.

Sat Sep 28 01:16:42 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/generic/strsep.c: Rename to __strsep and make strsep
	weak alias.
	* string/string.h: Add prototype for __strsep.
	* misc/mntent_r.c: Use __strsep instead of strsep to keep
	namespace clean.

	* sysdeps/stub/nanosleep.c: Rename to __libc_nanosleep and make
	__nanosleep and nanosleep weak aliases.
	* sysdeps/unix/sysv/linux/syscalls.list: Add __nanosleep as weak
	alias.
	* sysdeps/unix/sysv/linux/sleep.c: Call __nanosleep instead of
	nanosleep to keep namespace clean.

	* sysdeps/posix/ttyname.c (ttyname): Add cast to prevent warning.
	* sysdeps/posix/ttyname_r.c (ttyname_r): Likewise.
	* sysdeps/posix/getcwd.c (__getcwd): Likewise.

	* sysdeps/unix/nlist.c: Use ISO C definition since we don't always
	have prototype.

	* login/Makefile (headers): Add pty.h.
	* login/pty.h: New file.
	* sysdeps/generic/pty.h: Include <pty.h>.
	* login/pututline_r.c: Add cast to prevent warning.

	* gmon/gmon.c: Add prototype for __profile_frequency.

Sat Sep 28 00:11:08 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/syscalls.list: Add weak alias
	`adjtimex'.
	Set caller for mlock, mlockall, mremap, munlock, and munlockall
	to EXTRA.
	Reported by Matthias Urlichs <smurf@smurf.noris.de>.

1996-09-27  Paul Eggert  <eggert@twinsun.com>

	* strftime.c (strftime): Output incomplete formats like %E
	at end of string.

1996-09-27  Paul Eggert  <eggert@twinsun.com>

	* strftime.c (strftime): Add support for %EC and %Ey.
	Fix support for %EY.  This uses the new _nl_get_era_entry function.

Fri Sep 27 14:12:27 1996  Ulrich Drepper  <drepper@cygnus.com>

	Security related patch by Elliot Lee <sopwith@redhat.com> and
	David Holland <dholland@eecs.harvard.edu>.

	* inet/rexec.c (rexec): Increase size of `num' array from 8 to 32.
	* inet/ruserpass.c (ruserpass): Don't allow $HOME envvar to not exist.

	* sysdeps/generic/getenv.c (__secure_getenv): New function.  Return
	NULL when programs runs with SUID or SGID enabled.
	* sysdeps/stub/getenv.c: Make __secure_getenv an alias of getenv.
	* stdlib/stdlib.h: Add prototype for __secure_getenv.

	* locale/setlocale.c: Use __secure_getenv.
	* resolv/res_init.c: Likewise.
	* resolv/res_query.c: Likewise.
	* inet/ruserpass.c: Likewise.
	* sysdeps/posix/tempname.c: Likewise.
	* malloc/mtrace.c: Likewise.
	* catgets/catgets.c: Likewise.

	Make temporary file handling functions reentrant.

	* stdio-common/tmpnam.c: Rewrite to have own buffer to write
	result to.  The called __stdio_gen_tempname function must be
	thread safe.
	* stdio-common/tmpnam_r.c: New file.
	* stdio/stdio.h: Add prototype for `tmpnam_r'.
	Change prototype for __stdio_gen_tempname.
	* stdio/libio.h: Likewise.
	* sysdeps/posix/tempname.c: Add new parameters and use them instead
	of static buffer.
	Don't reset `indeces' when PID changed between calls.
	Don't fail for long running programs when index counter once
	reached the limit.
	* sysdeps/stub/tempname.c: Likewise.
	* stdio-common/tempnam.c: Provide local buffer as extra argument
	to __stdio_gen_tempname.  This makes this function reentrant.
	* stdio-common/tmpfile.c: Likewise.
	* stdio-common/temptest.c: Provide extra argument to
	__stdio_gen_tempname.
	* manual/filesys.texi: Describe tmpnam_r and add comments about
	reentrancy of the functions.

	* inet/rcmd.c: Fixed address length handling.

	* sysdeps/posix/mk-stdiolim.c: Count final \0 byte in L_tmpnam value.

	* time/strftime.c: Remove unused variables alt_digits and
 	end_alt_digits.

	* sysdeps/unix/sysv/linux/sys/sysinfo.h: Correct prototype names
	for get_nprocs and get_nprocs_conf.
	* sysdeps/generic/sys/sysinfo.h: Likewise.

	* stdlib/test-canon.c: Finally do the right fix.

	* misc/Makefile: Only compile force-wrapper when compiling
	reentrant libc.
