I recently had to build gcc 3.2.2 on an FC4 box. This failed using gcc
4.0.2 as the bootstrap compiler since gcc 3.2.2 uses no-longer-accepted
extensions. So I built gcc 3.4.5 using 4.0.2, and used that to bootstrap
3.2.2.
Now, if it is part of the release criteria that release N-1 must be

This shows pretty clearly that you haven't looked at it - the
basic bootstrap targets are about 10% of gcc/Makefile.in, which is
rather more than 30 lines.
You're right that I hadn't looked recently and it has indeed grown.
Certainly more than 30 lines, but not quite 10%: I count 375 o

This patch is okay.
(Though please try to watch the sniping in the future, there is no need
to be uncivil).
And don't you think that talking about compatibility expected by our
users is just a little bit disingenuous, when you're talking about
running make inside the gcc subdirectory? Users don't do that!
Only developers of GCC do. It's only useful for incremental builds; a

The answer to both of these questions is the same. Toplevel bootstrap
deliberately - as a design decision, and in my opinion, a very good
one - puts every stage in its own directory.
Of course: we've always had each stage living in a different directory.
You're not going to get any

The top level bootstrap model is to rebuild all the useful bits of the

be able to compare them.
