Updated ghc-6.0 windows installer available

[Sigbjorn Finne]

To fix a pair of showstopper bugs, an updated version of the
win32 MSI installer has been uploaded. It includes the following
fixes:

  - as was, -fvia-C fell over due to header files not being in the
    expected place within the install tree.
  - The ghci wrapper now quotes the command-line arguments that
     it passes on. This, hopefully, fixes the handling of filenames
containing
     spaces.

For people that have already downloaded the distribution &
don't want to redo it, here's how to patch an installation tree:

   - create /path/to/ghc-6.0/gcc-lib/include
   - move /path/to/ghc-6.0/gcc-lib/*.h to \
              /path/to/ghc-6.0/gcc-lib/include/
   - compile up the attached ghci wrapper, thusly:

       foo$ /path/to/ghc-6.0/bin/ghc -o ghci ghci.c
       foo$ cp ghci.exe /path/to/ghc-6.0/bin/

       (Note: this'll give you an icon-less version of the GHCi wrapper.)
