The problem is in scanner.get. Notice how
it creates scanner_id, and then uses the
unmangled scanner_name to search the cache.
The result is that when CompileAction adds
the <include> path from the <implicit-dependency>,
it's ignored. Honestly, I don't see how this
ever worked at all, since it means that all
targets of the same type get the same search path.
