Hi again Stuart,

I've findally gotten around to look into this again (sorry about that),
and it looks like the problem is simply in the final linking step: you
link all the .o files together.  But instead of linking each .o file once,
you link them for every occurrance in the dependency tree.

Simply deduplicate "object-files" in "compile-file" and you'll be fine.

Cheers,
Peter
