Comment:

 No, you misunderstand:

 i am saying that when I explicitly tell ghc to use either gcc-4.8 or
 clang, through -pgmc gcc-4.8  or -pgmc clang
 along with say trying the approach described in
 [http://stackoverflow.com/questions/2528887/c-compiler-selection-in-cabal-
 package this stack overflow discussion], ghc is still using the cc1 of
 gcc-llvm-4.2, which was used to build the ghc.

 I will attach the dtrace logs from my -fllvm and -pgmc clang run to
 provide proof of this.

 let me restate this: GHC ignores what compiler i tell it to use when it
 reaches the point where cc1 is called. There is no "default", there is a
 hard coded BUG.
