warning: comparison of unsigned expression < 0 is always false

[Alec Clews]

I'm getting the following warnings

../std_lib_facilities.h:112:8: warning: comparison of unsigned expression < 0 is always false [-Wtautological-compare]

                if (i<0||size()<=i) throw Range_error(i);

                    ~^~

../std_lib_facilities.h:118:8: warning: comparison of unsigned expression < 0 is always false [-Wtautological-compare]

                if (i<0||size()<=i) throw Range_error(i);

                    ~^~

Which if you look at the code make perfect sense as i is declared unsigned. Is there some reason it's written that way or can I remove the offending test?

Thanks

Hi.

You can remove the test.
