Compile error when disabling C++11 support

[CarterLi]

Simple test case:

~/cppformat-master/build % cat test.cpp
#include "../format.h"

int main() {
    fmt::MemoryWriter m;
    m.write("Test");
}
~/cppformat-master/build % clang++ test.cpp ../format.cc -o test
test.cpp:5:7: error: no matching member function for call to 'write'
    m.write("Test");
