Windows Build setupTools

One of the reasons I would like to eliminate Cygwin is that I believe it causes more problems than it is worth.  For example, lat time I check, there was a bunch of code in the build scripts to hack paths because Cygwin apparently wants non-Windows paths on Windows.  It’s the “let’s pretend we aren’t on Windows and make a mess” strategy employed by Cygwin that I find counter-productive.  (As a developer, I do like having common Un*x tools installed, but I prefer Windows ports of those tools that understand how to properly run on Windows instead of creating some virtual unix environment that doesn’t quite fit.)

I suspect a lot more build logic could be done within the Gradle scripts rather than using external tools.  That would result in a more portable build experience with less places for things to go wrong.
