[vtk-developers] Errors when compiling VTK v6.0.0 in C++11 mode

[Kevin Funk]

Hey list,

Compiling VTK v6.0.0 with C++11 mode enabled results in the following 
compilation error:

Since there are C++11 checks all over the code base I'd assume one can compile 
VTK in C++11 mode.

Is that a known issue? I didn't find a bug report for this one.
