 Attempting to compile CarpetLib with gcc 4.8 leads to the error

 /Users/ian/Cactus/arrangements/Carpet/CarpetLib/src/prolongate_3d_rf2.cc:501:56:
 error: 'static_assert' was not declared in this scope

 I had not come across static_assert before.  Apparently it is a C++11
 feature.  gcc 4.6 was able to compile it, but it looks like gcc 4.8 is
 stricter.  Do we want to require -std=c++11, or should we avoid C++11
 features for now?
