FWIW, Windows 7 "Enterprise" is supposed to ship with Microsoft's Unix compatibility bits, so conceivably no MKS or Cygwin would be required.

Moving to VS 2010 isn't ready yet. You'd be welcome to try, and give us feedback, but we're still not ready to migrate from VS 2003 as the "official" C++ compiler yet. It works, sorta, but there's still a fair number of bugs getting the whole system working properly. We're also looking at updating the SDK at the same time, so there's issues around that, too (though, less so). And, of course, we're looking at changing the build OS itself from Windows 2000 to something a bit more modern. And, the latest Cygwin has issues, too. I don't want to sound negative, because there really has been progress made. It's just that we need to update a whole bunch of things, and Windows is a real pain, compared to the other OSes we support. The jist of this is this: we're actively working on updating the Win32 and Win64 build setups (all aspects) to something that we can likely live with for at least a few more years. It's not done yet. It's also not quite up to just the RE Team to OK the switch - there are other stakeholders which have to OK it too. Kelly will have to speak as to the official adoption of VS2010 when it actually happens. -- Erik Trimble Java System Support Mailstop: usca22-123 Phone: x17195 Santa Clara, CA No virus found in this incoming message.
