xmodmap has no effect on mouse buttons

[Takuma Murakami]

At line 2912 in xc/programs/Xserver/dix/events.c
the function CoreProcessPointerEvent reads:

#if !defined(XFree86Server) || !defined(XINPUT)
            xE->u.u.detail = butc->map[key];
#endif

This code remaps mouse buttons.  For XWin.exe the
symbols XFree86Server and XINPUT are both defined and
this remapping is not performed.

I think this has something to do with the problem but
I don't know whether it is an expected behaviour or not.
Could anyone help me?
