clang warnings

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

Hi,

Cloning the fresh GHC source, I can validate GHC HEAD on Linux. And I
understand "install   dir" is correct.

The problem on Mac is that "ghc-clang-wrapper" is a shell script.  I
cannot find a way to treat strings, which includes spaces, correctly
with shell scripts.

So, I replaced "install dir" to "install_dir" in three files and
can validate GHC HEAD on Mac finally.

Questions:

* What is the purpose of spaces in "install   dir"?

* Would you tell me the plan to provide C preprocessor program by GHC
  itself?
