I've just committed this change to ctypes\wrap\codegenerator:

The codegenerator now by default assumes 'char *' and 'wchar_t *'
types are pointers to zero-terminated strings.  It generates

   STRING = c_char_p
   WSTRING = c_wchar_p

and STRING / WSTRING is used instead of POINTER(c_char) and
POINTER(c_wchar).

Maybe you can try it out by getting this file via viewcvs, once that
version 1.6.2.5 appears on the anon CVS servers:

http://cvs.sourceforge.net/viewcvs.py/ctypes/ctypes/ctypes/wrap/codegenerator.py

There's not yet a command line option to switch it off, you have to set
the global variable ASSUME_STRINGS to False in this file to revert to
the previous behaviour.  I hope that is what you need.
