Portions of GCC are distributed under the following license:

However, this notice does not seem to exist anywhere in binary distributions. I suspect the *intent* was similar to a BSD-style license, and my impression is that corporate lawyers tend to argue for that interpretation; i.e. "preserved" means that the notice is present somewhere in derivative works. Upstream, however, seems to feel that the notice is "preserved" because it hasn't been removed from the source file, i.e. it is *not* necessary to include the notice in binary distributions or other derived works.
If I ship compiled code which includes code under the above license, what are my obligations? Do I need to include the above notice? Can I omit it entirely? Something else?
