Re: Building ghc-0.29 for on sunos4 and linux

[Simon L Peyton Jones]

What is happening is this.

- there's a SPECIALISE pragma involving data type Reg in FiniteMap
- SpecTyFuns imports FiniteMap
- Haskell 1.2 required closure on import, so Reg therefore had to
  be imported even though it's not used.  Haskell 1.4 doesn't have
  this silly restriction.

Solution: import AsmRegAlloc( Reg ) into SpecTyFuns (and maybe elsewhere)
or remove the SPECIALISE pragmas in FiniteMap (easier; and you won't lose
a lot of performance).

How this ever worked is beyond me!
