Comment(by carter):

 I'm able to suppress the spurious CPP warnings clang gives by wrapping
 clang in the following script
  and then on my mac I can use the patched Clang instead of gcc to build my
 haaskell code fine with GHC 7.6.3
 {{{
 #! /bin/sh
 clang  -Wno-unicode  -Wno-trigraphs -Wno-invalid-pp-token  -Wno-return-
 type $@

 }}}
