Thanks, that worked!  Do you think you could update the Unicode section
in the WineLib user's guide (section 2.2)?  It doesn't even mention
WINE_UNICODE_NATIVE (not like the rest of the guide is that current,
but every little bit helps for new developers).

If you are using --fshort-wchar you should also use WINE_UNICODE_NATIVE
so that WCHAR gets defined to wchar_t. From winnt.h:

typedef wchar_t         WCHAR,      *PWCHAR;
typedef unsigned short  WCHAR,      *PWCHAR;

and further down:

 * - your compiler provides a 16bit wchar_t type, e.g. gcc >= 2.96 with
 *   -fshort-wchar option
 * - or if you decide to use the native 32bit Unix wchar_t type. Be aware
 *   though that the Wine APIs only support 16bit WCHAR characters for
 *   binary compatibility reasons.
 * - or define nothing at all if you don't use Unicode, and blissfully
 *   ignore the issue :-)

Does that help?
