Is it possible to get Cabal to use 'cl' (Microsoft's C/C++ compiler shipped with Visual Studio Express)?

The problem is to get GHC to use 'cl'. That's a longer term project that GHC HQ are interested in. There's something about it on the GHC dev wiki I think. Don't hold your breath.
When using the native code generator only foreign C code must be compiled with a C compiler. Presently Cabal passes C sources that are listed in the 'c-sources' field of a cabal file to GHC. It would be nice to have a Cabal field to specify the compiler for C sources, say 'c-sources-compiler: msvc'. The default would still be gcc, but with a Cabal flag the user would be able to change that to e.g. Sun's C compiler.
It would be reasonable to use the system C compiler rather than ghc, however we will have to do more work to find what extra include dirs get used and have Cabal pass those. Currently we pass the -package flags to ghc which ghc uses to look up what include dirs those packages add, and then it calls the C compiler with those extra include dirs. Cabal would have to do that itself. Duncan
