/* This is the Jmakefile for the library stuff.
   This stuff is all written in (Glasgow-extended) Haskell.

Everything here *must* be compiled w/ the Glasgow Haskell compiler.
(Hence the use of $(GHC), rather than $(HC) [the latter is your "standard"
Haskell compiler -- whatever you've configured]).

If you use EXTRA_HC_OPTS on the command line (which you shouldn't,
strictly speaking), it will probably work -- it is pinned onto
GHC_OPTS, just for fun.
