#include "cstring"
is the more C++-ish way to include it.
The first lines in gcc 10, the version I have here, corresponding file are
quite instructive:
#pragma GCC system_header
#include <bits/c++config.h>
#include <string.h>
#ifndef _GLIBCXX_CSTRING
#define _GLIBCXX_CSTRING 1
// Get rid of those macros defined in <string.h> in lieu of real functions.
#undef memchr
...
After this point it undefines a lot of macro and then replaces it by real
functions. As an example consider the first macro to be removed the
corresponding code then becomes:
extern "C++"
{
namespace std _GLIBCXX_VISIBILITY(default)
{
using ::memchr;
...
