I found a few more `issues' after adding `-O3 -Wall'.
Most are cosmetic, but the missing return value in remove_file_from_cache() is
a real bug. Hmm, upon closer look the caller uses its return value in a weird
way, so another bug may be hiding in add_file_to_cache().
Caveat: everything is untested, besides compilation ;-)
