Miles Bader 02eec64431 *** empty log message ***
Thu Jun  6 07:32:14 1996  Miles Bader  <miles@gnu.ai.mit.edu>

	* resolv/gethnamaddr.c (struct hstorage): Make NAME field a pointer.
	(_gethtbyname2): Remove ALIAS variable.
	Initialize NAME field of SELF and TARGET to 0.
	Add SELF_NAME_SIZE static variable.
	Add loop to call gethostname until the space we allocated is enough.
	Use malloced strings instead of fixed size buffers.
	<stdlib.h>, <unistd.h>: New includes.
	* sysdeps/generic/sys/socket.h (PF_INET6, AF_INET6): New macros.

	* sysdeps/mach/hurd/errlist.c (_sys_errlist): Add EILSEQ.
	(_sys_nerr): Initialize to 107.
	Update _HURD_ERRNOS consistency check.

	* stdlib/canonicalize.c (canonicalize): Use pathconf for PATH_MAX,
	not sysconf.

	* login/login.c [!PATH_MAX] (PATH_MAX): Define to be 1024 if not
	already defined.

	* sysdeps/mach/hurd/setitimer.c (timer_thread): Supply SIGCODE
	argument to __msg_sig_post_request.

	* hurd/hurdmalloc.c: Changes to bring in line with the hurd
	libthreads/malloc.c:
	(more_memory): Use assert_perror instead of MACH_CALL.
	"cthread_internals.h": Include removed.
	(realloc): Use LOG2_MIN_SIZE.
	(LOG2_MIN_SIZE): New macro.
	(realloc): Don't bother allocating a new block if the
 	new size request fits in the old one and doesn't waste any space.
  	Only free the old block if we successfully got a new one.
	[MCHECK] (struct header): New type.
	(union header): Only define if !MCHECK.
	(HEADER_SIZE, HEADER_NEXT, HEADER_FREE, HEADER_CHECK): New macros.
	[MCHECK] (MIN_SIZE): Add correct definition for this case.
	(more_memory, malloc, free, realloc): Use above macros, and add
	appropiate checks & frobs in MCHECK case.
