This is strange. I've all kinds of trouble getting hc-bootstrapping back
(for OpenBSD, but also in general), and I didn't see *that* problem.

But it just doesn't make sense at all. You need a good set of shell
commands at all, since they're used by configure as well as in
Makefiles. I really can't believe that simple stuff like this doesn't
work on windos:

ifBuildable.hs is similar; it can be replaced by a shell script or even
done within libraries/Makefile using very basic shell commands.

How is ghc currently built on windows without something like cygwin?

Or am I missing something really crucial here?
