[vtkusers] Can we drop Visual Studio 6 support?

[Bill Lorensen]

With ITK, if we have a VS6 or Borland or mingw or cygwin or VS7 or SUN
CC or 64 bit ICC or ... problem, we ask someone that has the compiler
to investigate a fix. Some errors are hard to fix without access to a
compiler.

If you are still having a problem,  I have a VS6 compiler and can try
to track it down for you.
