[Bug c++/45553] New: Warning Suppression: C++ Templates, Unsigned, and "comparison of unsigned expression < 0 is always false"

Hi All, A way to suppress the warning generated from the following would be a welcome addition. A solution was proposed in [1], but I'd like a cleaner approach. I believe suppressing the warning for a template parameter is the cleanest way to dispose of the warning. template< class T > SomeClass:

--- Comment #3 from pinskia at gcc dot gnu dot org 2010-09-06 05:39 --- It is still a dup of bug 11856. Note the use of bug here is really dealing with how do you describe all issues (enhancements or otherwise). The use is not saying it is a "software bug" in the normal sense. *** Thi
