Are full paths really necessary for that? OMake understands make's "-w" 
command-line option, and I was under impression that this is sufficient 
(I do not use emacs myself, so I am not 100% sure).

Right:
- This call does not create the %.cmx: %.ml rules (it just takes 
advantage of the already existing rules), so adding an explicit absname 
would not affect the compilation step

- By default, OCamlProgram _sorts_ the .cmx/.cmo files (according to the 
dependencies order) to help satisfy OCaml's link ordering requirement, 
and the inputs and outputs of the sorting process are interpreted as files.
