[A26] {PB} This was necessary for libc5, but is not correct when using
glibc. Including the kernel header files directly in user programs
usually does not work (see Q21). glibc provides its own <net/*> and
<scsi/*> header files to replace them, and you may have to remove any
symlink that you have in place before you install glibc. However,
/usr/include/asm and /usr/include/linux should remain as they were.
