Description

ghc --make should not recompile unnecessarily. Yet every build of the base package (for exanple) says: 

Preprocessing library base-2.1...
Building base-2.1...
[  2 of 166] Compiling GHC.Err[boot]    ( GHC/Err.lhs-boot, nothing )
[  4 of 166] Compiling GHC.Unicode[boot] ( GHC/Unicode.hs-boot, nothing )
[ 15 of 166] Compiling Data.Typeable[boot] ( Data/Typeable.hs-boot, nothing )
[ 23 of 166] Compiling Data.Dynamic[boot] ( Data/Dynamic.hs-boot, nothing )
[ 35 of 166] Compiling Foreign.Storable[boot] ( Foreign/Storable.hs-boot, nothing )
[ 40 of 166] Compiling GHC.TopHandler[boot] ( GHC/TopHandler.lhs-boot, nothing )

There is something wrong with the compilation manager. It's more of an infelicity than a bug, but it's still unsatisfactory.
