We mentioned this +briefly earlier, but a slightly more in-depth explanation of the fixincludes +process is warranted here. Under normal circumstances, the GCC fixincludes +script scans your system for header files that need to be fixed. It might find +that the Glibc header files on your host system need to be fixed, fix them and +put them in the GCC private include directory. Then, later on in Chapter 6, +after we've installed the newer Glibc, this private include directory would be +searched before the system include directory, resulting in GCC finding the +fixed headers from the host system, which would most likely not match the Glibc +version actually used for the LFS system.</para> + <para>The last patch changes GCC's default location of the dynamic linker, a simple substitution of "/lib/ld-linux.so.2" with "/stage1/lib/ld-linux.so.2" in <filename>config/i386/linux.h</filename>.
