This matter is muddy; fair use, interoperability, and copyrights of
header files and/or their contents is a legal mess.

Our policy is simple: paste-copy of any portion of any proprietary
licensed header is unwanted and will be systematically rejected. You
need to implement your own header, defining what you need for satisfying
all the references within the emulator your are writing from scratch.

You should also explicitly mention in the copyright notice that the
resulting software is an emulator. We claim to mimick the original
software as correctly as possible, according to the API specs which have
been made publically available by the copyright holder of the original
work, with all the limitations inherent to such exercise. In any case,
we don't claim to produce a copy of the original software we only
emulate. In short, Xenomai is a Chameleon, not a clone.
