no these are really missing include files in your sources.
What I've seen up to now were roughly 90% of either missing
"#include <cstring>" or "#include <cstdlib>".

well, "function not declared" has been an error in C++ before.

What changed is that some files are not any longer pulled in automatically
by others to get closer to the standard (please correct me here if I'm wrong).

Unfortunately I don't see how a compiler should do something like
 "include this header but prefix all declared functions with a warning" ...
