IMHO these are worth fixing. All the integer truncation warnings of - Wconversion would be worth fixing as well if we would expect indices towards 4294967296, but I guess that this does not happen anywhere in LyX. In a different context I did already experience real bugs because of such a truncation. > I wonder though why MSVC only gives a few of them. I do not wonder at all about MSVC warnings anymore. Some are really good, others are crap and need to be disabled explicitly. Georg
