I've managed to get all the unit tests working (except parser-test) and
the CORBA transport layer usable under windows.

The patches are available on github (branch rtt-2.0-mainline) :
http://github.com/jsreng/orocos-rtt

In a nutshell:
* Some "program" tests (program-test, state-test) were broken due to
inaccurate timer functions. parser-test still raises the same exception as
http://www.orocos.org/forum/rtt/rtt-dev/bug-723-new-parser-testexe-fails...
* Due to some windows weirdness with the Winsock includes and ACE, I
used the win32.h file to try to include some headers as earlier as possible
