Hi, Few trivial patches and a one-line fix for Paths_.hs stuff. (Duncan, four first are the ones I sent in an earlier, temporary, bundle.)

For most compilers this is currently just a static list. For ghc 6.7 and above we query ghc to find the list of language extensions it supports. In each case the code has moved out into the compiler-specific modules and the core code treats it generically. The extensionsToFlags function has been split into two: extensionsToFlags which now returns the flags for the supported extensions and unsupportedExtensions which does what it says it does. This is because the two roles of the previous function were always used separately, never together. ] [Use String rather than importing a module just to misuse a String type alias Duncan Coutts **20070807170526] [Add a little documentation.
