In 5.04.x you have to manually bootstrap - that is, you have to have two
build trees, and you build the compiler in the second tree using the
compiler built in the first tree.

In the current CVS sources, the procedure is somewhat easier: a 'make'
from the top-level will automatically to a 2-stage bootstrap, and there
are options for doing 3-stage or just a 1-stage build too.
