Attached a patch that seems to fix his problem. Then:
{{{
compiler/nativeGen/AsmCodeGen.lhs:594:17:
Warning: Defined but not used: `addr'
compiler/nativeGen/AsmCodeGen.lhs:601:17:
Warning: Defined but not used: `addr'
<no location info>:
Failing due to -Werror.
}}}
A second attached patch fixes this. Third:
{{{
compiler/nativeGen/AsmCodeGen.lhs:76:1:
Warning: The import of `opt_Static'
from module `StaticFlags' is redundant
<no location info>:
Failing due to -Werror.
}}}
Fixed by the third patch attached. Fourth:
{{{
compiler/vectorise/Vectorise/Utils/PRDict.hs:16:1:
Warning: The import of `TyCon' is redundant
except perhaps to import instances from `TyCon'
To import instances alone, use: import TyCon()
compiler/vectorise/Vectorise/Utils/PRDict.hs:17:1:
Warning: The import of `Outputable' is redundant
except perhaps to import instances from `Outputable'
To import instances alone, use: import Outputable()
<no location info>:
Failing due to -Werror.
}}}
Fixed by a fourth patch. Then:
{{{
compiler/vectorise/Vectorise/Utils.hs:7:3:
Warning: `prDFunOfTyCon' is exported by `module
Vectorise.Utils.PRDict' and `module Vectorise.Utils.Base'
<no location info>:
Failing due to -Werror.
}}}
Which a fifth patch fixes. And:

(This was also reported in http://www.haskell.org/pipermail/cvs-
ghc/2010-December/058433.html.) With a sixth patch, we get past this
obstacle as well.
