Comment(by chak):

 Stephen, it's great to see progress on this!

 I had a look at the patch (well, actually the `master-merge-ios` branch in
 the ghc-ios repo on !GitHub) and noticed that the changes in
 https://github.com/ghc-ios/ghc/blob/master-merge-
 ios/compiler/deSugar/DsForeign.lhs hardcoded iOS-specific settings, which
 can be traced back to this patch: https://github.com/ghc-
 ios/ghc/commit/6f01b16ba94c275683fccdc748f0b6e95f94e5d0 (e.g., the setting
 of `libFFI` and the removal of `insertRetAddr`) — it might be worthwhile
 to double check that that patch didn't hardcoded platform-specifics in
 other places as well. Do you know how to get at the platform info in
 `DsForeign`?

 Moreover, my compile dies with
 {{{
 Configuring ghctags-0.1...
 Configuring ghc-pwd-0.1...
 Configuring ghc-pkg-6.9...
 Configuring hsc2hs-0.67...
 Configuring haddock-2.13.2...
 ghc-cabal: At least the following dependencies are missing:
 terminfo -any
 make[1]: *** [utils/ghc-pkg/dist-install/package-data.mk] Error 1
 make[1]: *** Waiting for unfinished jobs....
 make: *** [all] Error 2
 }}}

 (I wonder why we are using crappy Trac instead of !GitHub for such
 discussions?!?)
