The problem seems to be in "cpp-options" field in glib.cabal where "__attribute__(A)" is redefined to nothing. This seems to cause problems only with head GHC because in head MinGW that comes with GHC is upgraded to 5.2. Simply removing that redefinition from .cabal fixed problem for me. Note that you will need to do the same thing for pango and gio packages.

(See complete log for command './Setup build -v3' attached) I should add that I'm rather a beginner with regards to the Haskell language and its package distribution system cabal.
