I think it's a bug when a compiler doesn't
understand an intermediate file it generated a
few minutes before. According to GHC:
> Window.hi:114:
> The constraint `GUIState.GUIObject Window' does not mention any of
> the universally quantified type variables {v}
> In the interface signature for `$fHasTextWindow'
Line 114 of Window.hi says:
> 1 zdfHasTextWindow :: __forall [v] {GUIValue.GUIValue v, GUIState.GUIObject Window}
>=> {GUIBaseClasses.HasText Window v} ;
ghc --version says
> The Glorious Glasgow Haskell Compilation System, version 4.03, patchlevel 0
I downloaded it around 18th May from the CVS repository and compiled it
for sparc-solaris.
What is going on? Thanks for your help.
