ANN: C-Haskell 0.8.1
I am pleased to announce the availability of version 0.8.1 of the interface generator C-Haskell. It works with the current stable release series 4.08.x of GHC as well as the current development series 4.11. For both versions of GHC, it supports the *same* FFI library that GHC natively only supports in the development version 4.11 and which constitutes the result of the work of the FFI Task Force over the last couple of months. The interface specification of the library is online available at http://www.cse.unsw.edu.au/~chak/haskell/c2hs/docu/c2hs-4.html For more information on C-Haskell and for downloading, see http://www.cse.unsw.edu.au/~chak/haskell/c2hs/ The main feature in this release is the new FFI library. It should allow users of the GHC stable series to use the new FFI library interface, which we hope to keep stable from now on. An update of the C-Haskell tool proper is being worked at.

Typing f.e.d.
I have a small change request regarding foreign export dynamic. Currently the FFI doc says: topdecl : ... .. | 'foreign' 'export' [callconv] 'dynamic' varid :: prim_type - IO Addr GHC additionally allows: prim_type - IO Ptr As usual the FFI "looks through" newtypes. But now that we have FunPtr, the following typing makes much more sense: 'foreign' 'export' [callconv] 'dynamic' varid :: prim_type - IO (FunPtr prim_type) where both prim_types have to be the *same*. We should probably allow the old Addr-typing as well for some time to facilitate the transition, but not the Ptr-typing (bleeding edge people will know what to do :-). The corresponding changes to GHC look easy, so I'd like to commit this if there are no objections. Furthermore, the FFI docs still talk about Addr only, not Ptr/FunPtr. Now that Addr is deprecated, this should be changed, too. Cheers, Sven ___ FFI mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/ffi

So, allowing Addr in f.e.d., or anywhere else for that matter, can only be for reasons of temporary backward compatibility.
