<pre>Well, this was a surprising result. I noticed it while troubleshooting an issue
where a lambda was not invoked. The lambda was guarded with a macro because the
code is both C++03 and C++11.
Testing on Fedora 27 with LLVM's Clang 4.0:
$ clang++ -x c++ -dM -E - < /dev/null | egrep '(clang|__cplusplus)'
#define __clang__ 1
#define __clang_major__ 4
#define __clang_minor__ 0
#define __clang_patchlevel__ 1
#define __clang_version__ "4.0.1 (tags/RELEASE_401/final)"
#define __cplusplus 199711L
Maybe it would be prudent to change to C++03 or C++11 by default in 2018.</pre>
