 I've built nearly every package on hackage to look for regressions. Two
 things need fixing:

 We do not look for `.h` files in the root directory of the package. This
 breaks `HsPerl5-0.0.6`, `cedict-0.2.5` and `halfs-0.2`.

 We do not add the include dirs for dependent packages. This breaks
 `hscurses-`, `plugins-1.4.0` and `unix-compat-`. Of these
 `plugins-1.4.0` is not a good test case because it is broken for other
 reasons (the .h file it #includes cannot be included on its own).

 The solution to the first issue should be easy. Just add `.` into the list
 of include dirs. The second requires copying the code from the pre-
 processor module where we do the same thing for hsc2hs. Perhaps it's
 possible to share the code.
