   This should work to install the deps, using libs from cygwin
 
-	cabal install libxml-sax --extra-lib-dirs=C:\\cygwin\\lib --extra-include-dirs=C:\\cygwin\\usr\\include\\libxml2
-	cabal install gnuidn --extra-lib-dirs=C:\\cygwin\\lib --extra-include-dirs=C:\\cygwin\\usr\\include\\
-	cabal install gnutls --extra-lib-dirs=C:\\cygwin\\lib --extra-include-dirs=C:\\cygwin\\usr\\include\\

   While the 1st line works, the rest fail oddly. Looks like lack of
-  quoting when cabal runs c2hs and gcc, as "Haskell Platform" is
-  taken as 2 filenames. Needs investigation why this happens here
-  and not other times..
+  quoting when cabal runs c2hs. This can be worked around by
+  unpacking the tarball, manually running c2hs, and deleting the .chs
+  files.

   Also needs gsasl, which is not in cygwin.
