[Insight-developers] Warnings in itkNumericTraits.h

[Williams, Norman K]

If you use '-Wall -Wextra' when you compile, every place
itk::NumericTraits::SetLength() is defined for a scalar type, it throws a
warning:

ITK/Modules/Core/Common/include/itkNumericTraits.h:243: warning: unused
parameter 'm'


You can preserve the function signature and get rid of the warning by
leaving the parameter anonymous, I.e.change

  static void SetLength(ValueType & m, const unsigned int s)


to
  static void SetLength(ValueType &, const unsigned int s)


Does anyone think that is a bad idea?  It is responsible for thousands of
warnings in a -Wall build.
