Does your Coccinelle support OCaml?  I'm not sure what is the proper way to
check for this, but in my coccinelle/config.log file I have

FEATURE_OCAML='1'

spatch --version gives:

spatch version 1.0.6-00147-g19f9421 compiled with OCaml version 4.02.3
Flags passed to the configure script: [none]
Python scripting support: yes
Syntax of regular expresssions: Str

I'm not sure why it doesn't give feedback on whether OCaml scripting is
supported.  I will check on this.
