test2/intern/cycles/kernel/closure/bsdf.h
Brecht Van Lommel c18712e868 Cycles: change __device and similar qualifiers to ccl_device in kernel code. 
This to avoids build conflicts with libc++ on FreeBSD, these __ prefixed values
are reserved for compilers. I apologize to anyone who has patches or branches
and has to go through the pain of merging this change, it may be easiest to do
these same replacements in your code and then apply/merge the patch.
