AFAIR MSys's rxvt.exe uses libW11.dll, which implements Xlib API on top of Win32 USER/GDI (no extra X server). However, it could be still difficult (probably because of API name clashes?) Not sure why the message is about libX11.dll - probably it sees $DISPLAY and tries to use real X?
AFAIR rxvt can be used both with and without X server, so that's probable.
