and like the gcc 3.2 change over, the upstreams will eventually have to make this change as well so Debian can help out and make this task easier for them. However, are these new lexer files backwards compatible? I would have a hard time getting an upstream to accept a patch that would prevent their source from building anyhere but the new flex.
