New Linux System calls (*at) in 2.6.16

[Troy Rollo]

Google for these combined with keywords related to Wine didn't show anything, 
which surprised me since they seem ideal to solve a number of problems. A 
bunch of new calls have been added to the Linux kernel 2.6.16 
http://lwn.net/Articles/164887/ that are mirrors of the existing system 
calls but take a file descriptor for a directory that becomes the base point 
for relative paths.
