Perhaps a good solution would be to have a separate make rule for
generating the AST code (i.e. not included in the overall dependancy
graph).  That increases the chance that they don't get regenerated
when they should but people hacking on the AST files should notice
the error pretty easily.  Other people should always be able to
build from the files checked in to SVN and so having the dependancy
there is just a source of trouble.
