add skeleton for new attrib.exe application

[Juan Lang]

Hi EA, some comments on your tiny little app:

+#define WIN32_LEAN_AND_MEAN
+
+#include "config.h"
+
+#include <windows.h>
+#include <stdio.h>
+#include <stdlib.h>

You don't need to define WIN32_LEAN_AND_MEAN for compiling with Wine's
headers, and you don't need to include <windows.h>, either.  Also,
since you never use any of the standard library functions, you don't
need to include <stdio.h> or <stdlib.h>.  A useful starting point when
compiling with Wine's headers is:
#include <stdarg.h>
#include "windef.h"
#include "winbase.h"

+int main( int argc, char *argv[] )
+{
+    exit(0);

As Jeff pointed out in bug 18059, just return 0 rather than calling
exit(0).  I don't think you need to use wmain rather than main for an
empty application, but if you ever intend to work with the command
line, wmain is probably better.
