darcs patch: added cppOptions and c2hsOptions

Here is what Cabal does:

$ ./Setup.lhs -v build
../src/Matlab/C/CMatrix.h: No such file or directory
Reading parameters from
Preprocessing library Matlab-0.0.1...
D:\Apps\MSYS\1.0\local\bin\c2hs.exe -C -D__GLASGOW_HASKELL__=606 -C
-Ic:\Apps\MATLAB704\bin\win32\..\..\extern\include -o
src\Matlab\C\CMatrix.hs src\Matlab\C\CMatrix.chs
D:\Apps\MSYS\1.0\local\bin\c2hs.exe -C -D__GLASGOW_HASKELL__=606 -C
-Ic:\Apps\MATLAB704\bin\win32\..\..\extern\include -o src\Matlab\C\CMat.hs
c2hs.exe: Matlab/C/CMatrix.chi not found in:

Setup.lhs: got error code while preprocessing: Matlab.C.CMat

Here is my command that works (from MatlabCompiling/test)

$ c2hs --cppopts=-I/c/Apps/MATLAB704/extern/include --include=../src

Here is the addition to matlab.buildinfo which makes Cabal work:

c2hs-options: --cppopts=-I/c/Apps/MATLAB704/bin/win32/../../extern/include

I'm also attaching a file which should recreate all the errors that I've
found on MinGW/WinXP.  Note that there are files outside the cabal hierarchy
to simulate headers/library which are already on the system and outside the
packager's control.
