Hi,
What change did we think we need for a GHC 7.6.4 to support Xcode 5? Was it just this change to fiddle with the command line options?
I don't know what is the best. But here is what I know now: clang-xcode5-wrapper.hs (*1) works as a wrapper in many cases so far. We need to change the value of "C compiler command" in settings(*2). Unfortunately, in some commands, hsc2hs for instance, the command name "gcc" is hard coded. So, clang-xcode5-wrapper.hs should be installed as "gcc". This "gcc" should have higher priority than /usr/bin/gcc in PATH. One concern is that users would get troubles with this new gcc.
