Hi Juanjo,

  I suspect a derivative question is to what extent people having to
write FFI functions using low-level utils can depend on the
stability of data structures defined in object.h.  For example, the
recent addition of Unicode support has the effect of chaning
ecl_array_datat members -- the 'ch' was gone -- therefore
breaking some FFI codes that depended on that.
