After a quick googling, there's no guarantee that you won't hit ABI
compatibility issues, i.e. that libraries that you use would have a
different ABI when compiled with C++11 and C++03. Boost is especially
problematic.

In addition, gccxml does not support C++11, so you'll have to avoid
C++11 in anything that orogen has to swallow until the clang importer
is released.
