To be clear, the C++ standard specifies what functions MUST be part of
a given include, but allow any other functions/symbols to also be
included. This is actually the main reason why "using namespace std"
is discouraged for beginners - because any header could import an
ungodly amount of symbols into the global namespace by doing that.

So yeah, it sounds like they cleaned things up and now improper C++ code breaks.

It's a good thing, if you ask me.
