Changes (by simonpj):
* status: new => merge
Comment:
OK first part (putting `SpecConstrAnnotation` in `GHC.Exts` is done),
which is enough for 7.0. I'll mark this as "merge" for now; then back to
'new' for part 2!

* Define SpecConstrAnnotation in GHC.Exts, and import it from there
Reason: avoid having to link the entire ghc package in modules
that use compile-time annotations:
import GHC.Exts( SpecConstrAnnotation )
{-# ANN type T ForceSpecConstr #-}
It's a kind of bug that the package exporting SpecConstrAnnotation
is linked even though it is only needed at compile time, but putting
the data type declaration in GHC.Exts is a simple way to sidestep
the problem
See See Note [SpecConstrAnnotation] in SpecConstr
M ./compiler/specialise/SpecConstr.lhs -37 +56
}}}
There's a similar patch in `base`:
