patch applied (cabal-branches/cabal-1.2): Actually -stubdir only works well in ghc-6.8 due to -I search dir mess

Wed Sep 26 06:18:43 PDT 2007 Duncan Coutts * Actually -stubdir only works well in ghc-6.8 due to -I search dir mess In ghc-6.6 the Foo/Bar.hc files only #include "Bar_stub.h" rather than #include "Foo/Bar_stub.h". This means when we set the stubdir so that the _stub.h files don't sit next to the .hs file then the include search path is not right to find the _stub.h file. In ghc-6.8 this is fixed so that it adds the -stubdir path to the include search path when calling gcc. M ./Distribution/Simple/GHC.hs -1 +1
