In octave-2.1.52 Debian and octave-cvs-2003-12-15, I can create
a structure element without specifying an index:

	octave:1> u.hour=1
	u =
	{
	  hour = 1
	}

I can modify that element:

	octave:2> u.hour=2
	u =
	{
	  hour = 2
	}

but I can't do the same for a structure returned from gmtime():

	octave:3> t=gmtime(0);
	octave:4> t.hour=1
	error: invalid structure assignment
	error: assignment to structure element failed
	error: assignment failed, or no method for `struct = scalar'
	error: evaluating assignment expression near line 2, column 7

unless I use an explicit index number:

	octave:5> t(1).hour=2
	t =
	{
	  hour = 2
	  isdst = 0
	  mday = 1
	  min = 0
	  mon = 0
	  sec = 0
	  usec = 0
	  wday = 4
	  yday = 0
	  year = 70
	  zone = GMT
	}
