Your current patch uses $hcflag variable.

But you forgot to use this variable in HCFLAGS.

So we need last patch's below part.

And I meet another problem in your patch.

$ runhaskell Setup.lhs build
(snip)
c:\ghc\ghc-6.8.2\bin\ar.exe: creating dist/wx/libwxcore0.a
ar -sr dist/wx/libwxcore0.a dist/wx/imports/Graphics/UI/WXCore/WxcObject_split/*
.o &&  ar -sr dist/wx/libwxcore0.a dist/wx/imports/Graphics/UI/WXCore/WxcClassTy
pes_split/*.o &&  :

Windows' ar can't use long argument.
And GHC uses xargs to avoid that problem.

http://darcs.haskell.org/ghc-6.8/ghc/mk/target.mk

Could you use xargs to link split-objs?
