The compiler flags in the Makefiles are set to "treat warnings as errors",
so your code won't even compile when warnings occur.
7. Miscellaneous notes
Each commit in your branch corresponds to a different VCSVERSION string
automatically defined in the header 'version.h' during the build. If you happen
to find it convenient to disable this feature it can be done using:
touch .git/wireshark-disable-versioning
i.e., the file 'wireshark-disable-versioning' must exist in the git repo dir.
