<para><userinput>patch -Np1 -i ../gcc-&gcc-version;.patch:</userinput>
This patch fixes a bug in gcc's linker concerning non-exported (weak)
symbols, which was brought to the surface by the new glibc.</para>
<para><userinput>--enable-languages=c,c++:</userinput> This only builds the C
and C++ compilers and not the other available compilers as they are, on
the average, not often used. If those other compilers are needed,
the --enable-languages parameter can be omitted.</para>
<para><userinput>ln -s ../usr/bin/cpp:</userinput> This
creates the $LFS/lib/cpp symlink. Some packages explicitly try to find
cpp in /lib.</para>
<para><userinput>ln -s ../bin/cpp:</userinput> This
creates the $LFS/usr/lib/cpp symlink as there are packages that expect
cpp to be in /usr/lib.</para>
