So, it is important that standard code not produce errors. Kinda fundamental. I think this should be fixed in some other way. If a type is to be used as a standard type, producing an error for that type's use is wrong. Instead, find a way (cough, __extension__), to mark or not warn (error) for it instead. > > Alternatively, I considered adding typedefs preceded by __extension__ to fix > these errors, but in many cases __SIZE_TYPE__ is directly used Can you fix __SIZE_TYPE__ itself to have __extension__ in it? If not, then I'd find another way to remove that warning for the type.
