-<para>If using the compiler optimizations provided in this chapter,
-please review the optimization hint at <ulink
-url="&hints-root;optimization.txt"/>.  Compiler optimizations can make
-a program run slightly faster, but they may also cause compilation
-difficulties and problems when running the program. If a package
-refuses to compile when using optimization, try to compile it without
-optimization and see if that fixes the problem. Even if the package
-does compile when using optimization, there is the risk it may have
-been compiled incorrectly because of the complex interactions between
-the code and build tools.  Also note that the <option>-march</option>
-and <option>-mtune</option> options may cause problems with the
-toolchain packages (Binutils, GCC and Glibc).  The small potential
-gains achieved in using compiler optimizations are often outweighed by
-the risks. First-time builders of LFS are encouraged to build without
-custom optimizations.  The subsequent system will still run very fast
-and be stable at the same time.</para>
