Follow the instructions in the `install' file, not the FAQ. It basically
worked fine for me, except that the files in the `cross' directory of
djcrx201.zip need to be moved/linked to the base directory before you do
anything else. Here are the commands I used for building a cross-compiler
hosted by i486-linux (Slackware 3.2). I used Binutils 2.7.0.9 (a version
specially patched for Linux) because I had it handy; it seems to work fine.

Eli, you may want to update the FAQ.

Oh yeah, one note: I think GCC might expect to be built with `cc'. If so,
just symlink `gcc' to `cc' and it works.

$ ls
djcrx201.zip    gcc-2.7.2.1.tar.gz      binutils-2.7.0.9.tar.gz
$ unzip -a djcrx201.zip   # The `-a' is important!
$ ln -s cross/* .   # These files belong in the top-level dir.
$ emacs makefile    # Edit per install file
$ tar xzf binutils-2.7.0.9.tar.gz
$ mv binutils-2.7.0.9 binutils-2.7 # To keep makefile happy.
$ tar xzf gcc-2.7.2.1.tar.gz 
$ patch <patch.lib
$ make all
$ make install  # You may need to run `su' depending on where you install.
