You're right. I wasn't completely clear.

Correct, but there's a different incompatibility I'm trying not to hit
upon: source incompatibility. It is not guaranteed that we can build all
the tools in the first place. Currently, it seems that upgrading from
2.2.8 cannot be done as-is, because we have gperf in the bootstrap-tools
and the native 2.2.8 C++ compiler doesn't grok its source. Building gcc
in the bootstrap-tools might solve this, but makes it all a bit more
hairy (we need certain tools in bootstrap-tools because we need to be
able to build gcc in the cross-tools).

The bottomline: Use what we can and rebuild only when necessary.

Oops. I forgot that we now build install-info... I'll fix it ASAP.

Thanks,
