That's correct.

The test case is wrong.  That is maybe left over from when cabal
didn't treat the main-is field correctly.  I just fixed that.

Hmm. From within buildGHC, I see:
  withExe pkg_descr $ \ (Executable exeName' modPath exeBi) -> do
...
                 let binArgs = 
...
                         ++ [hsSourceDir exeBi `joinFileName` modPath]


So I think we're OK.  Seems to work right:
./setup build -v3 
...
/usr/bin/ghc -package-conf /home/ijones/.ghc-packages -odir dist/build/./testB-tmp -hidir dist/build/./testB-tmp -o dist/build/./testB --make -i. -i. B/MainB.hs

(in this case, hsSourceDir is .)

peace,
