XCode 5

[Kazu Yamamoto 山本和彦]

Hi all,

To check ticket #8139, I'm wondering whether or not I should install
XCode 5 to my MacBook Air. I heard that GCC will be removed if XCode 5
is installed.  I also heard that if we modify "lib/settings" of GHC
7.6.3, GHC 7.6.3 can work with clang.

So, my question: how can I build GHC head with clang?
Is "make maintainer-clean; perl boot; ./configure" just enough?
Does "configure" automatically find clang and use it
if GCC does not exist?
