5<userinput>patch -Np1 -i ../gcc-3.0.patch:</userinput> This patch
6changes all instances of re_max_failures to re_max_failures2.
7re_max_failures is a variable used within Glibc and with static
8compiling this variable sometimes clashes between the package's
9re_max_failures and the same variable in glibc. By renaming
10re_max_failures in the package to re_max_failures2 we just tell the
11package to use the second variable so that glibc won't be in the way.

15<userinput>--enable-languages=c,c++:</userinput> This only builds the C
16and C++ compilers and not the other available compilers as they are, on
17the average, not often used. If those other compilers are needed,
18the --enable-languages parameter can be omitted.

28<userinput>ln -s ../bin/cpp:</userinput> This
29creates the $LFS/usr/lib/cpp symlink as there are packages that expect
