Building GHC head with clang on Mavericks

[Kazu Yamamoto (=?iso-2022-jp?B?GyRCOzNLXE9CSScbKEI=?=)]

Hi,

Adding the "-v" option, GHC displays:

----
*** Checking old interface for main:Lexer:
*** Parser:
*** Renamer/typechecker:

<built-in>:2:2: Not in scope: `#'
----

"-keep-tmp-files" keeps generated .hscpp file. The beginning of the
generated .hscpp is:

----
# 1 "utils/genprimopcode/dist/build/Lexer.hs"
# 1 "<built-in>" 1
# 1 "utils/genprimopcode/dist/build/Lexer.hs" 2
{-# LANGUAGE CPP,MagicHash #-}
{-# LINE 2 "utils/genprimopcode/./Lexer.x" #-}
----

"<built-in>:2:2: Not in scope: `#'" in my previous message indicates
this line 2.

I don't know why Renamer/typechecker cannot handle this .hsccp file.
