Attached. Changes against the compat-mode only patch are:
- ECPG_informix_set_var() and ECPG_informix_get_var()
  were renamed to ECPGset_var() and ECPGget_var() and
  were moved into libecpg. The previous calls are kept
  in libecpg_compat.so as wrappers for compatibility reasons.
- adjust_informix() was renamed as adjust_outofscope_cursor_vars()
  to indicate its real purpose. The comment at the beginning
  of the function is modified to explain why it's useful.

The code produced by this is not too ugly this way in
native mode, only some ECPGset_var() calls are added
when the DECLARE are in the same function as OPEN/FETCH/CLOSE.
Global variables used in DECLARE aren't transformed at all.
