37    kernel headers (straight from a kernel tarball) in <filename

39    years, the kernel developers have taken a strong stance that this
40    should not be done. This gave birth to the Linux-Libc-Headers Project,
41    which was designed to maintain an API stable version of the Linux
42    headers. But recently this project stopped producing updates. Cross-LFS
43    decided to come up with our own santized headers and placed them in
44    the book.</para>
