Are you include string.h or cstring?  You say string.h here, but the
errors below say cstring.  So, I'm a little confused.

I can't be sure without seeing the code, but my guess is that it is
complaining that it can't find `::size_t' and `::ptrdiff_t' because
those types have been wrapped in std namespace, but you are including
the non-namespace aware string.h header.  If this is the case and you
change all includes of the type

#include <string.h>

to 

#include <cstring>

and add a line such as this

using namespace std;

to each C++ file, I think you'll be good to go.  HTH.
