Perhaps so for 64-bit gcc (couldn't find it though) but I don't think anything can be done if the author is working on a 32-bit system where there is nothing to warn about. We just have to deal with the fact that different compilers emit different sets of warnings. > Incidentally, what do we do for Windows?

While I agree warnings should be fixed whenever possible, this seems counterproductive. It will simply cause libtiff to break all the time. Olivier
