An alternate tactic is to unpack the 2.2 kernel and run @samp{make
-config} as above; then, rename or delete @file{/usr/include}, create
-a new @file{/usr/include}, and make the usual symbolic links of
-@file{/usr/include/linux} and @file{/usr/include/asm} into the 2.2
-kernel sources. You can then configure glibc with no special options.

+After installing GNU libc, you may need to remove or rename
+@file{/usr/include/linux} and @file{/usr/include/asm}, and replace them
+with copies of @file{include/linux} and
+@file{include/asm-$@var{ARCHITECTURE}} taken from the Linux source
+package which supplied kernel headers for building the library.
+@var{ARCHITECTURE} will be the machine architecture for which the
+library was built, such as @samp{i386} or @samp{alpha}. You do not need
+to do this if you did not specify an alternate kernel header source
+using @samp{--with-headers}. The intent here is that these directories
+should be copies of, @strong{not} symlinks to, the kernel headers used to
+build the library.
Note that @file{/usr/include/net} and @file{/usr/include/scsi} should
@strong{not} be symlinks into the kernel sources. GNU libc provides its
