No, this would imply deleting the stage2 and stage3 compilers and that isn't
what happens. Instead the compiler of each stage is updated in isolation.
RIght. Thus I always blow away stage2-* stage3-*, and stage1 target
directories along with the "compare" stamp file.
Thanks (all of you). It's amazing that I have been getting away
with it for all these years.
Why is this not done automatically? I mean, what is the use case
for make bootstrap without doing these steps first?
