[vtkusers] Deprecated header usage

[Gib Bogle]

Building a program that uses VTK, I got this warning from gcc:

In file included from 
c:\mingw-4.4\bin\../lib/gcc/mingw32/4.4.0/include/c++/backward/strstream:46,

c:\mingw-4.4\bin\../lib/gcc/mingw32/4.4.0/include/c++/backward/backward_warning.h:28:2: 

warning: #warning This file includes at least one deprecated or antiquated 
header which may be removed without further notice at a future date. Please use 
a non-deprecated interface with equivalent functionality instead. For a listing 
of replacement headers and interfaces, consult the file backward_warning.h. To 
disable this warning use -Wno-deprecated.

I realize that isn't currently an issue.  Should I just ignore it, and use 
-Wno-deprecated?

Thanks
