patch applied (cabal): Change the handling of cpp & ghc flags for hsc2hs

Tue Oct 16 16:16:52 PDT 2007 Duncan Coutts * Change the handling of cpp & ghc flags for hsc2hs The hsc2hs that comes with ghc uses ghc as the C compiler. This means we must escape the real cc flags. It also means we can ask ghc to add extra include dirs that we might need to find includes of dependent packages. This is a bit of a hack. In the longer term it'd be better for Cabal to collect the include dirs and cc options of dependent packages and to pass them explicitly itself. M ./Distribution/Simple/PreProcess.hs -20 +35
