That's the wrong part.

Build.hs has this logic:
odir | versionBranch ghc_vers >= [6,4,1] = pref
| otherwise = pref `joinFileName` dirOf c
-- ghc 6.4.1 fixed a bug in -odir handling
-- for C compilations.
which is good, but it only does that for libraries, not executables.
Damn. This needs to get refactored to share code.
I think I fixed this. Should be in the latest darcs and CVS. Andres,
can you try this and let me know?
