When building GCC 4.0.2, make fails with this error:

Why does this happen when I am able to build programs with the same includes?
"Some locales installed by the make localedata/install-locales command above are not properly
supported by some applications that are in the LFS and BLFS books. Because of the various
problems that arise due to application programmers making assumptions that break in such
locales, LFS should not be used in locales that utilize multibyte character sets (including
UTF-8) or right-to-left writing order." - LFS-BOOK 6.11. Glibc-2.3.4
I suppose that can be applicable to includes as well.
#include <iostream>
#include <string>
using namespace std;
int main(int argc, char** argv) {
string name;
if (argc > 1) name = argv[1];
else cin >> name;
cout << "Hello, " + name +"\n";
return 0;
}
here is the results
