Since GHC 6.14 will (hopefully) be use LLVM as a default backend, an idea has occured to me Should GHC also use the clang (C/C++->LLVM compiler) on external C library sources which are used with certain Haskell packages (such as gtk) when LLVM does become a default backend for GHC. The consensus is that since Clang will also produce LLVM 'assembler', it can be very easily linked with the LLVM 'assembler' produced by GHC's LLVM backend, making the process of using external C sources a lot easier. Parts of Clang required could even be integrated into GHC (although this may be tricky since its coded in C++). It should also hopefully make using Haskell packages on windows that use C sources less painful Clang could also make using FFI with C++ much easier (for reasons stated above) Thoughts?
