It's the exception:

  "if the cmo file is a camlp4 preprocessor (like Camlp4OCamlPrinter.cmo
   in OCaml), then it must be included because otherwise the syntax
   extension would not be available."

http://fedoraproject.org/wiki/Packaging/OCaml#head-acc221f1e087bc5ce860356b34823bb447da5df5

*.cmo files are loadable object files.  Camlp4 (the macro
preprocessor) loads the pa_openin.cmo file at runtime, which
modifies the actual syntax accepted by the compiler.

In this case it adds the useful 'open M in e' syntax so you
can open a module just for the bit of code that actually needs
it, not for the whole program.
