I see two options:

1. Use an alternative attribute syntax that works in C++03 mode
2. Don't provide `<system_error>` in C++03 mode, since it is technically a C++11 addition to the library

(2) is a lot harder and would be breaking for users. We could investigate doing that, but (1) would be significantly easier especially given the simplicity of the patch that motivates it.
