Hi,

Let me give you a status update on our work:

This has been completed meanwhile.

In addition, we've integrated contributions of Tor Lillquist and  
Ole André Vadla Ravnås.

As a result, internal testing indicates that the current dbus4win fixes quite 
some issues the Kontact on Windows windbus code still showed. Till can give 
details on what exactly we found has improved.

This is in an intermediate stage. At one point, cross-compilation worked, but 
it has since deteriorated again. We intend to fix this up again, but two of 
our engineers working on the projects are now going on vacation (me 
included), so it won't happen before the second half of June. The current 
state can be found in the dbus4win-xcompile2 branch.

Here, we're still working on both code and spec. For interested parties, the 
work is ongoing in branch dbus4win-noncetcp (that's nonce-tcp, not 
non-ce-tcp, we're doing tcp since that one _does_ work on WinCE :)

Thanks, and see you at the other side of vacation,
Marc
