I'll definitely defer to Claus on this one.  I'm still "working through
the issues" in places, but I don't yet have anything coherent to add.

(This was all motivated, btw, by trying to build HaXml under ghc/cygwin,
which fell for me at the first hurdle of "first catch your hmake" in the
recipe.  I've now gotten as far as a _build_ of hmake, but it then runs
into similar issues with its own use of the f/s (rc files and what-not).
If anyone has this one down pat already, they might save my tired brain
some pain, otherwise I'll summarise to the list if and when I get some
sort of resolution myself.)

Cheers,
Alex.
