Personally I believe there should be option with unbundled mingw (unless
it, which I don't think is a case except C++ in which GHC is not written
in, there are problems with mixing gcc versions). I find myself with
installed few different version of gcc/msys/perl/tcl/... in system just
because each program installs its own copy.

I'm even thinking about writing package manager for Windows to handle
the bundling problem but I don't think it'll succeed (Windows is not my
primary OS).
