Regression in xcode generation in 4.4 beta3

Hi! I've entered a bug in the tracker a while ago and I guess my description was a bit confusing. I've just attached a repro case for you:

https://sourceforge.net/tracker/index.php?func=detail&aid=3410213&group_...

It seems to be a very special case since we use premake to generate alot of different projects without problem. There is just one that doesn't work and the problem seems to be related to the directory structure.

Thanks.
