+<title>Installation of GCC</title>
+
+<para>This package is known to behave badly when you have changed its
+default optimization flags (including the -march and -mcpu options).
+Therefore, if you have defined any environment variables that override
+default optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting
+or modifying them when building GCC.</para>
+
+<para>This is an older release of GCC which we are going to install for the
+purpose of compiling the Linux kernel in <xref linkend="chapter08"/>. This
+version is recommended
+by the kernel developers when you need absolute stability. Later versions of
+GCC have not received as much testing for Linux kernel compilation. Using a
+later version is likely to work, however, we recommend adhering to the kernel
+developer's advice and using the version here to compile your kernel.</para>
+
+<note><para>We don't install the C++ compiler or libraries here. However, there
+may be reasons why you would want to install them. More information can be found
+at <ulink url="&blfs-root;view/stable/general/gcc2.html"/>.</para></note>
+
+<para>We'll install this older release of GCC into the non-standard prefix of
+<filename class="directory">/opt</filename> so as to avoid interfering with
+the system GCC already installed in <filename class="directory">/usr</filename>
+ .</para>
+
+<para>Apply the patches and make a small adjustment:</para>
+
+<screen><userinput>patch -Np1 -i ../&gcc-2953-patch;
+patch -Np1 -i ../&gcc-2953-no-fixinc-patch;
+patch -Np1 -i ../&gcc-2953-returntype-fix-patch;
+echo timestamp &gt; gcc/cstamp-h.in</userinput></screen>
+
+<para>The GCC documentation recommends building GCC outside of the source
+directory in a dedicated build directory:</para>
+
+<screen><userinput>mkdir ../gcc-2-build
+cd ../gcc-2-build</userinput></screen>
