[ITK Community] g++ 4.8 warnings - Locally defined typedefs but not used (ValueType, PrintType, ...)

[Jean-Christophe Fillion-Robin]

Hi Folks,

When compiling Slicer against the release branch of ITK, I get some
"-Wunused-local-typedefs" warnings (See below). Should I submit a patch or
is there a good reason to have these unused local typedefs ?

Compiler: g++ (Ubuntu/Linaro 4.8.1-10ubuntu8) 4.8.1

Thanks
Jc
