Thanks, I didn't know about that. This is my first time I've
successfully built Git on Windows, so I can't compare build systems.
(Makefile and CMake never worked for me.)

Out of curiosity, why are the integration tests so much slower on
Windows than Linux? Is it the 10+ ms overhead of creating each new
process? https://stackoverflow.com/q/47845/284795
