Anyone else seeing these warnings when compiling Wireshark on Windows?  I don’t see any of the CI jobs indicating these warnings, but maybe that’s because I’m running a newer version of the compiler, currently VS 2022 17.14.32 with MSVC 19.44.35227, whereas the CI jobs seem to be running MSVC 19.41.34123.0?
 
Build succeeded.
