Hi. I will double check ASAP, but definitely most of them are about signed -> unsigned, exactly like in this specific PR. A very common idiom in C++, as noted by Gaby. Probably, outside the "STL" there are also a few conversions from larger to smaller unsigned types, which I think we can certainly fix in the headers, being sensible warnings per the recent discussion. About the signed *constant* -> unsigned issue, I don't think (maybe Gaby can correct me) you can really tell it apart from the variable signed -> unsigned, because the optimizers can see a constant in an inline function thanks to constant propagation even if no constant is explicitely present in the code (I hope my technically rather imprecise wording is sufficiently clear, sorry) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30464
