New version requires C++11 support, would C++0x be sufficient out of necessity?

[mar-ses]

Since the recent updates, setup.py fails if the compiler doesn't have C++11 support (and seems to prefer C++14). Unfortunately, on one of the clusters I don't have C++0x support, with gcc 4.4.7. Apparently this is fairly close to C++11 standard, though only contains a subset of C++11.

If I rigged setup.py to bypass that check, would george actually fail to calculate or would there be some fatal errors?
