Check for case sensitive filesystem on OSX doesn't work.

[sffjunkie]

The check in the configure script for a case sensitive filesystem on OSX fails as the 'diskutil info' command (at least on Lion) requires a volume name not a directory.

As all OSX volumes are listed under /Volumes the volume for the current working directory can be found by using the first 2 elements of the path.

The attached patch should work.

Diff to configure command

TBH, I'm more inclined to remove the check completely. A case sensitive file system being a prerequisite is documented and there are other prerequisites we don't check for explicitly either.

That aside, I don't see why the check needs to be Darwin specific at all. Other systems support case insensitive file systems as well (FAT) and a case sensitivity check can easily be performed using touch and rm.

@Alex please check this bug, it relates to hrev44302
