Where is memcpy on Nano Every?

I tried different includes and all I get


Error (active)	E0020	identifier "memcpy" is undefined		

#include <string.h> does nothing
In fact it leads to String.h which includes string.h, but that is also leads to String.h, EH?

Please post an example sketch that displays the problem

I found this: String.h conflicts with <string.h> on case insensitive filesystems · Issue #37 · arduino/ArduinoCore-API · GitHub

Because Visual Studio on windows is case insensitive on includes it cannot resolve path to the C library because some very clever person didnt think people might use Arduino on windows PC with case insensitive filenames.

I'm livid.

Nevermind, the errors are from intellisense, but it compiles.
