In Mesos sources we use c-style C headers (<stdlib.h>), as opposed to c++-style (<cstdlib>). C++11 Standard 17.6.1.2 p4, p8, and reference 177 hint that cname is a preferred form for C++ programs. However this may require adding std prefix everywhere, since according to the Standard cname headers may not provide its declarations and definitions within the global namespace (C++11 Standard D.5 p3).
Basically, we have three options here: 1. Leave the status quo and stick to C-style headers. 2. Create a clean-up JIRA and follow up with the cleanup. 3. Start using cname headers with std prefix and do a smooth transition. Thoughts?
