These warnings seem to be related to Windows-specific {{{.dll}}} files, including {{{kernel32.dll}}}, {{{user32.dll}}}, {{{msvcrt.dll}}}, {{{advapi32.dll}}}, and {{{ws2_32.dll}}}. As far as I can tell, there are no problems other than the warnings themselves, but I can't be sure. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9297 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
