Don't *include* the shell scripts, but *link* to them.
This is for a reason: I manage them in a RCS and from time to time publish updates. They're not going to be maintained inside the wiki system, but will eventually be included in the Hurd's source code base.

-# * Thadeu Lima de Souza Cascardo for updating the instructions about getting
-# the source code of GCC using the Subversion repositories.
-
-# Prerequisites:
-#
-# A build environment for the system you're running the script on is required,
-# i.e. a C compiler with the basic libraries and `make'. You might also need
-# `flex' and `bison'.
-
-# Usage:
-#
-# Place `cross-gnu' and `cross-gnu-env' somewhere in `$PATH', e.g. in `~/bin/'.
-
-# Get the source code of the
-
-# * GNU Binutils, <http://gnu.org/software/binutils/>, `src/binutils'

-# $ svn co svn://gcc.gnu.org/svn/gcc/branches/BRANCH gcc
-# $ mv gcc BRANCH
-#
-# BRANCH is one of `gcc-3_3-branch', `gcc-3_4-branch', `gcc-4_0-branch',
-# `gcc-4_1-branch' or the tag of a released version like `gcc_3_4_3_release'.
-# Or fetch a tarball from <ftp://ftp.gnu.org/gnu/gcc/>.
-
-# * GNU C Library, <http://gnu.org/software/libc/>, `src/glibc'
-#
-# $ cvs -d:pserver:anoncvs@sources.redhat.com:/cvs/glibc \
-# co -r glibc-2_3-branch glibc
-# $ mv libc glibc-2_3-branch
-#
-# Change `glibc-2_3-branch' to `glibc-2_5-branch' to get the glibc 2.5 branch
-# or omit `-r glibc-2_3-branch' if you want to get the trunk, i.e. the glibc
-# 2.6 branch, but note that building both of them currently won't work
-# without heavy patching.
-#
-# Or fetch a tarball from <ftp://ftp.gnu.org/gnu/glibc/>.
-#
-# If you want to use GCC 4.1 or newer, you'll also need to apply the

-# <http://nic-nac-project.de/~schwinge/tmp/init-first.c_vs._GCC_4.1.patch>.

-# Create a directory where the cross build shall take place and `cd' to that
-# directory. Create a subdirectory `src' and create symbolic links for every
-# of the above packages: from `src/PACKAGE' to where you stored or unpacked it.
-# If you don't intend to build several cross compilers or use the source trees
-# otherwise, you can also directly store the source trees in `src/'. The
-# source trees can be shared between multiple cross build trees since the
-# package's build systems are supposed not to modify the files in the source
-# trees. Not all packages adhere to that, but they fail to do so only for
-# pre-processed documentation, etc., as far as I can tell.
-
-# Run
-# $ ROOT=. cross-gnu
-# ... to create the cross build environment in the current directory from the
-# sources in `src/'.
-
-# Later, run
-# $ ROOT=WHERE_THE_ROOT_OF_THE_CROSS_BUILD_TREE_IS; . cross-gnu-env
-# ... to set up `$PATH' (and some other environment variables; have a look at
-# cross-gnu-env), so that you can easily use e.g. the cross compiler running
-# `$TARGET-gcc'.
-
-# Notes:
-
-# You can re-run `cross-gnu' to rebuild the parts of the sources that have
-# changed since the last run. This might save a lot of time and is especially
-# useful if you aren't working with unpacked tarballs, but on CVS's branches or
-# want to quickly get a new tool chain with patches you applied to the source
-# trees.
-# I would, however, _not_ recommend to use this technique when doing major
-# changes to the source trees, like switching from gcc-3.3 to gcc-3.4.
