Sorry, above change is not working. Assertion fail for
WINPROC_AllocProc((WNDPROC)newval,(WNDPROC)newval);

in /user32/winproc.c function alloc_winproc()
--------------------------------------------------------
        if (funcA && funcW)
        {
            assert( builtin_used < BUILTIN_WINPROCS );  <----------------
            proc = &winproc_array[builtin_used++];
            proc->procA = funcA;
            proc->procW = funcW;
            TRACE( "allocated %p for builtin %p/%p (%d/%d used)\n",
                   proc_to_handle(proc), funcA, funcW, builtin_used,
BUILTIN_WINPROCS );
        }
--------------------------------------------------------

It seems we can only assign procA and proW for built-in class 
at initial call registration.

I am still wonder how windows did this:

After Edit class is subclassed with a Unicode procW, how come the
CreateWindowExA still create Edit window as ANSI.
