 I did a first pass at back-porting Austin's clang-compatibility patches
 from HEAD to 7.6.3 in anticipating of a 7.6.4 release, or at least some
 sort of update for OS X 10.9 folks.

 The back-ported commits are on branches in my GHC GitHub repo:

 https://github.com/darinmorrison/ghc

 ghc-7.6.3-clang (just clang stuff)
 ghc-7.6.3-clang+mavericks (clang stuff + 10.9 fixes)

 I haven't tested this fully yet, or even compiled it yet with the latest
 changes, but I think I caught most of the stuff that might cause problems.

 (Actually I just tried now and there's another error further along I still
 need to track down.)

 There are a few other rough edges still: warnings, etc. Also, if you want
 to use the validate script, you'll need to turn off Werror. Anyway, I'll
 try to get remaining stuff sorted out and get some binaries up in the next
 couple of days.
