If updated and existing tree to the autoconf branch you might need to
use the -dP option to cvs update. It's probably best to just do a clean
checkout of the branch though.

The devtools/gen-avr-lib-tree.sh script is definitely in cvs though.

To build a cross-compiler with the configure generated by the newer
autoconf/automake tools, you have to specify --build and --host and they
must be different. I tried really hard to have it automagically set in
configure.ac, but they've changed the internals making it difficult if
not impossible to do.

The new avr/ dir is created and populated by the
devtools/gen-avr-lib-tree.sh script. I did this to avoid creating the
tree in cvs only to be told it's a bad implementation (i.e. to keep the
cvs repo cruft to a minimal if my idea is crap).
