OK. That is very nice. So, I know, that this change was not the problem.

The difference for coLinux 0.7.1 and 0.7.3 are very small. Mostly are
fixups for compiler warnings.

There exist an other interesting change between versions:
http://colinux.svn.sourceforge.net/viewvc/colinux?view=rev&revision=574

This sets the 10.0.2.2 as source for broardcasts. Perhaps somethin is
wrong there? I will check it with netcat and tcpdump next times.
