Windows build gets stuck with cmd prompt

[rtrusso]

If the git/usr/bin binaries are in the path, GNU make will launch git/usr/bin/sh.exe to interpret commands in the makefile, instead of using the Windows build in cmd.exe. There appears to be some kind of issue in sh.exe where it won't pass the arguments to cmd.exe correctly, so cmd.exe obediently drops to a prompt and waits for input.

For now the workaround is to (temporarily) remove that from your PATH and try building again.

I'm looking at some ways to reduce dependencies or use a dependency that is better supported on Windows for the Windows build.
