Building the tools on Windows is still slow(ish) because the POSIX 
emulation layer is being used. The build systems the tools use have lots 
of shell execs for tests and other things and this slows things down.

The MinGW64 tools we build do not suffer from this and when combined 
with a native Windows build system tool like waf or cmake you get nice 
fast application builds.
