Hi Michael,

zlib 0.5.3.2 builds fine, with ghc 7.0.4 Cabal-1.10.2.0 it just needs
some help to find the header file containing the macros generated by
cabal.  To avoid the error:

Stream.hsc:86:21: error: missing binary operator before token "("

in the Gentoo Haskell overlay I pass this extra option to the
runghc ./Setup.hs configure:

--hsc2hs-options=--include=${S}/dist/build/autogen/cabal_macros.h

where ${S} is the source code directory.

With ghc 7.2.2 and 7.4.1-rc2 it compiles fine with or without
this configure option.
