New description:

 on windows xp/7/8 when path to local cabal packages contains russian
 unicode characters, some of packages with dependencies fail to link.

 local cabal install path is in user directory on windows,
 like C:\Documents and Settings\леново\Application Data\cabal\
 and ghc fails like this:
 {{{
 loadObj "C:\\Documents and
 Settings\\\1083\1077\1085\1086\1074\1086\\Application
 Data\\cabal\\primitive-0.4.0.1\\ghc-7.0.4\\HSprimitive-0.4.0.1.o": failed
 }}}
 some of packages that fail:
 vector
 alex

 not works on haskell platform 2011.4.0.0, 2011.2.0.1

 log:
