Visual Studio 2010

[Kelly O'Hair]

Windows 7 might be a fine build system for developers to use, but as  
far as a formal Release Engineering
build system, I don't think we will be able to use it and still  
deliver bits that would still run reliably on Windows XP systems.
The build systems are historically the older systems, and if  
developers use Windows 7, it's ok, but it will always be
critical that the builds on Windows XP always work, so the developers  
will need to be careful.

As far as the Microsoft Unix compatibility bits go, I would love to be  
able to use it, but I could never get it to work in the past, and
it was never clear to me that it provided all the basic unix utilities  
we needed, it seemed to be more focused on getting the
two OS's to interoperate instead of providing basic unix tools.

And with each flavor of windows unix tool set, we seem to end up with  
more cruft in the makefiles to deal with the minor or major
differences between them all. :^(
