I think the issues you raise are in addition to make_host.  make_host
should just say "ms-windows" or "ms-dos" (_not_ the same) or "cygwin"
or "gnu/linux" etc.  This is enough to determine things like $EXEEXT

We could then make more feature variables, like posix etc., or maybe a
system_features variable that is a list, which could be used to
fine-tune the Makefile.  (For knowing what shell is available one can
simply use $SHELL, so I'm not sure anything else is needed.)

And what about make_version?
