Msys + mingw - is there an installer or at least .tar.lzma / .zip?

I am trying to install the nth time msys + mingw - but with little success. I need a minimal developer system (standard tools like sed / awk + autotools + gcc), but every time something doesn't work (for example, currently, when I try to run autotools, m4 goes into some kind of error loop in AC_INIT).

I know they stopped providing the installer "for easy component updates" and they work something, but maybe there is something unofficial.
