The inclusion of the GHC made config.h in HsFFI.h makes it extremely difficult to use autoconf with ones own projects without dealing with horrible name clashes everywhere. Is there some way this can be fixed? perhaps pre-generating the HsFFI.h. although I don't think it is stated explicitly by the FFI report, I would assume that HsFFI.h should not clash with anything that doesn't start with Hs, hs_ or HS_. also, it would be good if config.h could be renamed to something like ghc-config.h, because otherwise the conflict between the names can hide bugs where you get the incorrect config.h or make it tricky to get at the GHC one if it is actually the one you want.
