[Hat] hmake -hat looks for file in /usr/include, not PWD

[David Morse]

"hmake -hat -package GLUT Main" fails with: "Fail:
/usr/include/hat/DoublyLinked.hx: openFile: does not exist (No such
file or directory)".  DoublyLinked.hs is sitting right in the
directory from which I'm compiling, I'm not sure why the -hat flag
causes this digging in /usr/include.  Deleting "-hat" causes
successful compilation.

The directory tree looks like this:
lanes/
ByKey.hs  DoublyLinked.hs  IfPrime.hs  Main.hs  MaybeBool.hs
Traffic.hs Traffic/
lanes/Traffic/
Data.hs  Sim.hs  Units.hs

This is hat 2.02-12 and hmake-3.09-3 on Debian stable x86.

This is the full text of the build:

in Traffic/Sim.hs the line including DoublyLinked looks like this:
"import qualified DoublyLinked as DL"
