Sacha Labourey reported problems building master on Window due to failures in the osgi module testsuite. I fired up my old XP machine and was able to reproduce. A snippet from the console output showing the first failure:

Sacha said he was running 64 bit so he was presumably on a newer environment than my 2005 Windows machine. :-)
