1999-07-06  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/alpha/ioperm.c: Update for some more
	motherboards.
	Patch by Jay Estabrook.

	* sysdeps/unix/sysv/linux/configure.in: Don't test for libc4 in
	ldd for SPARC.
	* /sysdeps/unix/sysv/linux/sparc/ldd-rewrite.sed: New file.
	Patch by Cristian Gafton.

1999-07-02  Cristian Gafton  <gafton@redhat.com>

	* sysdeps/unix/sysv/linux/bits/socket.h (__cmsg_nxthdr): "return 0"
	instead of "return NULL" to make C++ happy.

1999-07-04  Mark Kettenis  <kettenis@gnu.org>

	* libio/iofdopen.c (_IO_new_fdopen): Set EINVAL if MODE is not
	allowed by the file access mode of the open file.

1999-07-06  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/generic/setfpucw.c: Include math.h to get all needed
	macros defined.

1999-07-03  Jakub Jelinek   <jj@ultra.linux.cz>

	* sysdeps/sparc/sparc64/submul_1.S: Fix carry handling. Optimize.
	* sysdeps/sparc/sparc64/lshift.S: Make a leaf subroutine. Optimize.
	* sysdeps/sparc/sparc64/rshift.S: Likewise.

1999-07-04  Wolfram Gloger  <wmglo@dent.med.uni-muenchen.de>

	* malloc/malloc.c (request2size): Check for overflow and return
	NULL whenever it is encountered.

1999-07-04  Zack Weinberg  <zack@rabi.columbia.edu>

	* sysdeps/posix/tempname.c (__gen_tempname):   Add
	ability to create directories.  Replace OPENIT and LARGEFILE
	args with a single flags parameter.
	* sysdeps/generic/tempname.c: Likewise.
	* include/stdio.h: Adjust prototype of __gen_tempname to
	match.  Define symbolic constants for second argument.

	* misc/mkdtemp.c: New file, provides new function mkdtemp().
	* stdlib/stdlib.h: Prototype it.
	* misc/Versions: Export it.
	* misc/Makefile (routines): Add mktemp.
	* manual/filesys.texi: Document it.

	* misc/mktemp.c: Adjust call of __gen_tempname to match new
	convention.
