Hi,

Wed May  4 18:41:44 PDT 2011  intractable@gmail.com  * intrapackage-deps-and-per-component-preprocessing  This patch adds intrapackage dependency resolution so that components  (libraries, exes, test suites) are build in the correct order.  This mean it's  now possible to have, e.g., executables that depend on other executables defined  in the same package description: the build-tools namespace has been extended  accordingly.

 Related to this change is the refactoring of the do-it-all preprocessSources  function, formerly invoked by initialBuildSteps, into a a function  preprocessComponent that is invoked when a component is being built.  This lets  us use executables defined in a package to be used as a custom preprocessor when  building other components.

 Finally, a number of functions now operate on values of the sum type  PackageDescription.Component rather than specifically operating on Library or  Executable and so forth.

This patch seem to have broken preprocessing somehow. With it, Cabal is unable to build ghc-paths: Building ghc-paths-0.1.0.8... Preprocessing library ghc-paths-0.1.0.8...
