You describe the bootstrap, all right.  However, if a previous version 
of GCC is already installed, you don't need all those steps.  You can 
simply do stage 1 and 2, or even directly stage 2.

That's how all versions of GCC up to (and including) 2.8.x were
compiled for DJGPP.  I do the same on Unix if some version of GCC
is already available.
