I=E2=80=99m not sure, but I got the shadowing to work.  In fact, you don=E2=
=80=99t need
shadowing at all.  You can just pass =E2=80=9C--with-hsc2hs=3D/gnu/store/..=
.=E2=80=9D as a
configure flag:

    (arguments
     `(#:configure-flags
       (let ((hsc2hs (assoc-ref %build-inputs "ghc-hsc2hs")))
         (list (string-append "--with-hsc2hs=3D" hsc2hs "/bin/hsc2hs")))))

Unfortunately, it doesn=E2=80=99t help.  Looking at the source code, =E2=80=
=9Chsc2hs=E2=80=9D
*is* calling GCC with a response file.  AIUI, GCC is supposed to
continue to use response files for all of its subprograms.  Hence,
everything should work.  I=E2=80=99m stumped.  :/

I=E2=80=99ll take another look with a fresh mind sometime, and see if I can=
 make
any progress.
