The CI jobs do have the warnings, but they go by quickly. It's in code only compiled by MSVC (not even by cross-compilers for Windows).

Those three were recently added. An underlying reason is that the Werror options are not applied in the extcap directory, which seems wrong.

The first warning from turning off warnings when compiling lemon is harmless, though with an annoying amount of effort it could be quieted.

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  I don’t see any of the CI jobs indicating these warnings, but maybe that’s because I’m running a newer version of the compiler, currently VS 2022 17.14.32 with MSVC 19.44.35227, whereas the CI jobs seem to be running MSVC 19.41.34123.0?
