It won't build on systems with compilers without C11 support.
Support for old style pthread based thread-local storage has been removed. Some of the shim code is still there to provide destructors on thread exit.
This means thread-local storage, C99 initializers, C11 atomics, etc. All of these features make it easier for us to maintain the server.
So anyone running RedHat 6 is sol. Sorry, but that's life.
Unless you run clang, which does implement the basic features of C11 on RHEL6.
Or build yourself a non-prehistoric version of GCC. (along with the many dependencies it requires) I've been using 3.1 on RHEL 6.4 for a while now, it builds and works fine. :) This message contains information that may be privileged or confidential and is the property of the Capgemini Group.
