HEAD version hsc2hs malfunction

[Peter Simons]

I have problems with the current HEAD version when compiling
my ADNS bindings <http://cryp.to/hsdns/ADNS.hsc>. It appears
that ghc has stopped passing the correct search path
automatically, because with the new version I had to add an
explicit "-I/home/simons/projects/foo" when compiling, or it
wouldn't find the _stub.(c|h) files. Once I had that sorted
out, I got this:

  /tmp/ghc12865.hc: In function `s8Ej_ret':
  /tmp/ghc12865.hc:6355: error: `ADNS_d7gS' undeclared (first use in this function)
  /tmp/ghc12865.hc:6355: error: (Each undeclared identifier is reported only once
  /tmp/ghc12865.hc:6355: error: for each function it appears in.)

Is this a bug in the compiler? In hsc2hs? My fault?
