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,
