---------------------------------

I could build clang++ 3.5. My clang version

clang++ --version
Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin14.1.0

> Compiling 0.23.0 (rc1) gives me compilation errors on Mac with clang 3.5. It looks like
the issue was introduced in a5640ad813e6256b548fca068f04fd9fa3a03eda, https://reviews.apache.org/r/32838.
In contrast to the commit message, compiling the rc with gcc4.4 on CentOS worked fine for
me. 
> According to 0.23 release notes and MESOS-2604, we support clang 3.5.
