For ghc --make you simply get wrong results (it does not track when you change compile options).
Which is relevant in sophisticated cases. I'm concerned that cabal makes simple things more complicated than they need to be.
Just to note, this is not a model we ever intend to support in the "Simple" build system. Build systems should be purely functional. The one concession we will need to make to a purely functional description is the ability to specify exceptions that some changed input will not trigger another function to be recalculated (eg while hacking, temporarily specifying that stage1 of a compiler changing will not cause rebuild of stage2).
... Heh. Should I be opening a separate ticket? :)
Probably. A common section is not a bad thing. Note that this would not give any sharing of build results. It's just a shortcut to putting the same options in each section. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/89#comment:24 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
