Someone said that they =E2=80=9Cagree with the reasoning=E2=80=9D, but the = original patch does not provide one. It looks like it's about preventing the use of compiler-supplied header files, but even that doesn't really answer the question: why? Especially since some parts of the kernel actually need some of those header files. Thanks, Florian
