Ah, but of course! :-)    I'm happy now!

Now it works, at least for dlls/kernel/tests/file.c

If you compile with:

i586-mingw32msvc-gcc -o FILE.EXE -DREAL_EXE file.c

The magic is the defines of ok, todo_wine and START_TEST.

See this as proof of concept, I'm sure someone can make this
look better.

(If you have Debian 3.0, just "apt-get install mingw32-runtime mingw32".)

How do I make this happen automagically when doing "make tests"?

#ifndef REAL_EXE

#include "winbase.h"
#include "winerror.h"
#include "wine/test.h"

#else

#include <windows.h>
#include <stdio.h>
#define ok(val, msg) {if (!(val)) {printf ("%s\n", msg);} }
#define todo_wine
#define START_TEST main

#endif /* REAL_EXE */

#include <stdlib.h>
#include <time.h>
