I get those on Windows when compiling with IPv6 support enabled:

This is not a problem when using GCC 4.7, but it IS one with GCC 4.4 (the compiler shipping with the current Qt SDK on Windows).

@sipa I'm not sure if this needs fixing, but I dunno how anyway. If you consider this to be a non-issue just close it!

This warning doesn't happen with recent MinGW version. @sipa Should this be fixed and if no you are free to close this!
