Vim is early on so if something goes wrong, you have
an editor available to fix it. I do not have vim installed
but I suspect that like most console editors it requires ncurses.

gcc can be compiled with static or dynamic mawk. I would prefer
compiling gcc as soon as possible because the dynamic version
is more efficient with memory than the static. (I know the
same is true of mawk, but gcc is bigger). The difference is
is compile times is probably too small to measure, so there
I do not see a good reason to recommend changing the book.

Yes it could be. Why bother?

For a list of things that need ncurses, type:
for file in /bin/* /sbin/* /usr/bin/* /usr/sbin/*; do
if ldd $file | grep ncurses >/dev/null; then

What for? We already have gcc doing a bootstrap. gcc compiles itself,
then uses the result to compile itself again. If there is any difference
between the two sets of gcc binaries, the bootstrap process should
report this as an error.
