[vtkusers] about the conflict between the new IO and the old IO

[Luis Ibanez]

Hi Yixun,

You should simply enable the use of ANSI_STDLIB
when configuring VTK.

Chances are that you are mixing new and old
#includes for header files in your application.

Please identify a minimal piece of code where
you observer this behavior and post the code
to the list.


   Thanks


     Luis
