There is a big difference between upgrading a library and switching to
a new language specification. For starters, C++03 and C++11 are ABI-
incompatible on most implementations that I know of. That means that before
you can even compile your code in C++11 mode, every library and piece of
code that your code links to must also be recompiled in C++11 mode. You can
see how that might take a while to happen in a large organization.
