It seems that GHC 6.6 just enables -fglasgow-exts when it sees any LANGUAGE pragma, so not all of them were added; this patch adds the rest of them, which is necessary for xmonad to compile in GHC >=6.7.

-- A layout that splits the screen into a square area and the rest of the
|
|
-- screen.
|
|
-- This is probably only ever useful in combination with
|
|
-- "XMonadContrib.Combo".
|
|
-- It sticks one window in a square region, and makes the rest
|
|
-- of the windows live with what's left (in a full-screen sense).
