GHC targetting Java?

[John Goerzen]

Hi,

I just noticed the GhcWithJavaGen in mk/config.mk.  It sounds
interesting and useful.  I decided to switch it on and experiment, but:

Could not find module `PrimRep':
  use -v to see a list of the files searched for
    (imported from javaGen/JavaGen.lhs)

It seems that I'm missing some needed files.  Any idea where I'd find
them?  Any other reference on the Java target from GHC?

(This is GHC 6.4.1)

Thanks,

-- John
