You are trying to compile an outdated version of Xenomai, Xenomai
version 2.5 or earlier. You can have access to the installation
instructions for that particular version in the sources (the file is
named README.INSTALL at the top of the sources tree), or on the
website, using the URL:

http://xenomai.org/documentation/xenomai-2.5/README.INSTALL

for instance, if installing the version 2.5. Replace 2.5 with the
version you are actually installing.
