Can't do that on a clean source tree, you need to ./configure first.

Again, this requires msys and GNU make to start with. I want it to work
without those completely. And the script I have now does this just fine,
it just needs some cleanup work and the removing of a couple of
hardcoded things.
A lot of space in it right now is because I list each project manually
in the beginning (postgres, one for each binary in bin/ etc) because the
makefiles aren't entirely consistent for that. And it also gorws a bit
because the conversion procs are built a different way...
