The macOS build slave is coping, according to the CMake output it's using:

-- The C compiler identification is AppleClang 11.0.0.11000033
-- The CXX compiler identification is AppleClang 11.0.0.11000033

on osx-10.14-x64.  Presumably that's an older OS.

This particular failure can be fixed by this: https://code.wireshark.org/review/36921

However, I get other failures afterwards:

Hi,

I was aware of such a problem. The travis macOS builder got that while ago.

https://travis-ci.org/github/crondaemon/wireshark

I didn't bisect, but going back in build history, I looks something between 2acbaf584984828855a36105258033020f338c5c and d30a0a2ce7c17f5d695e9ee7647e92d3cc1156bb.

Hi,

I'm have been building on macOS Mojave for a while without issues, but for the last few days the build has been broken. I didn't try a git dissect yet to see which commit broke it, but the issue seems to be caused by the usage of the _Nonnull, _Nullable, or _Null_unspecified type specifiers in the 6lowpan dissector.

My compiler is:

> gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1

Target: x86_64-apple-darwin18.7.0

InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

This is the error:

This code builds on Linux, and I assume some older version of macOS on the buildbots too. Should I give it a go to fixing this? I'm not the 6lowpan dissector author/maintainer.
