Am I missing some complication I'm not aware of?

In my experience this warning is just about always the result of
using int for variables which should be of type size_t, as in

  for(int i=0; i<object.size(); i++) 

If I cannot redefine all the types to unsigned, something like this
usually fixes the problem:

  if ( size >= 0 && static_cast<size_t>(size) < object.size() )

Writing static_casts is annoying, but it is often necessary
if you want to remain -Wall -pedantic.
