#124: Windows installer messes up directory structure
-------------------------------+--------------------------------------------

Component:  Windows installer  |    Keywords:        
-------------------------------+--------------------------------------------
 The Windows installer for the Platform 2010.1.0.0 messes up the directory
 structure so that *.h files installed with the extralibs are not found
 when installing packages with cabal-install.

 The files are searched in {{{$platform\extralibs}}}, but they are
 installed in {{{$platform\lib\extralibs}}}.

 === Error Message ===

 {{{
 > cabal install digest
 Resolving dependencies...
 Configuring digest-0.0.0.8...
 cabal: Missing dependency on a foreign library:
 * Missing header file: zlib.h
 This problem can usually be solved by installing the system package that
 provides this library (you may need the "-dev" version). If the library is
 already installed but in a non-standard location then you can use the
 flags
 --extra-include-dirs= and --extra-lib-dirs= to specify where it is.
 cabal: Error: some packages failed to install:
 digest-0.0.0.8 failed during the configure step. The exception was:
 ExitFailure 1
 }}}

 === More Information ===

 Note that on Windows, digest depends on zlib, which contains a source
 distribution of zlib. So the missing zlib.h has been installed with the
 Haskell Platform.

 {{{
 > where /R c:\Haskell\Platform\2010.1.0.0 zlib.h
 c:\Haskell\Platform\2010.1.0.0\lib\extralibs\zlib-0.5.2.0\ghc-6.12.1\include\zlib.h
 }}}

 However, cabal install passes {{{...\2010.1.0.0\extralibs\...}}} to gcc.

 As a quick hack, I copied the extra libs to the position where cabal
 install wants them, which allows me to install digest (and, in turn,
 pandoc).
