What steps will reproduce the problem?

Building git-annex on the ghc7.0 branch on a Mac with the default case-insensitive file system

What is the expected output? What do you see instead?

Expected: build successfully; instead:

ld: duplicate symbol _UtilityziDiskFree_zdwa_info in dist/build/git-annex/git-annex-tmp/Utility/diskfree.o and dist/build/git-annex/git-annex-tmp/Utility/DiskFree.o for architecture x86_64

What version of git-annex are you using? On what operating system?

commit 0bd5c90ef0518f75d52f0c5889422d8233df847d on a Mac OS 10.6 and 10.7, using the Haskell Platform 2012.04

Please provide any additional information below.

The problem is that since DiskFree.hs generates DiskFree.o and diskfree.c generates diskfree.o, a case-insensitive file system overwrites one object file with the other. Renaming diskfree.c to diskfreec.c and changing the corresponding filenames in git-annex.cabal fixes the problem.

Man, not this again. The 80's called, they want their unix portability wars back. fixed. --Joey
