[vtkusers] IRIX 6.5 build..

[Clinton Stimpson]

The setting is VTK_USE_ANSI_STDLIB.
If you are going to use the -LANG:std compiler flag, your code needs to 
be written to use the standard c++ library.
Which means you include <iostream>  not <iostream.h>  and you use 
std::ostream, not ostream.
Newer IRIX CC compilers have moved to using standard iostream by default 
(even without the -LANG:std flag), so you'll probably want to move in 
that direction too with your code.

VTK provides helpers for this kind of stuff.  See vtkIOStream.h and use 
vtkstd:: in your application if you want.
