Closing as invalid.

If you build with a C++03 standard library (libstdc++ 4.2), it's going to be
faster than with a C++11 standard library - because there's a lot more in the
library headers for C++11

Eric's tests, with a version of libstdc++ that implements the C++11 features,
show no difference in compile times.
