 TIA! I won't have enough time for much testing during the next few days
(for personal reasons), but I'll try to look at any problems you might find
with the compiler or wx update a.s.a.p.

 What about upgrading xmlwrapp to be able to use the recently added support
for RelaxNG schemas? If you'd like to do this too, we need to make a new
(0.9.0) release of this library too, as lmi installation currently uses a
release tarball (and I don't see any reason for changing this), please let
me know if we should.
