wdm doesn't start up correctrly

[Simon Alder]

After the last package update, WINGs display manager wdm doesn't work
correctly anymore. It just says "starting WINGs display manager: wdm"
but nothing happens. xdm and kdm work fine. I'm using woody with
XFree86-4.1.0-7. I already corrected the bug about $REALSTARTUP. What
went wrong?
