+commit 0a69fadadc5aacbd339f839ac5bd12c3571278b1
+Author: Sergey Sharybin <sergey.vfx@gmail.com>
+Date:   Thu Jan 9 15:50:11 2014 +0600
+
+    Fix compilation error on NetBSD
+    
+    - NetBSD doesn't provide sincos(3) in libm, so don't try to use it
+    - Use posix_memalign on NetBSD
+    
+    Original patch is by Jeorg Sonnenberger to Blender patch tracker, thanks!

-    Lint cleanup, mostly white space and line width.
-    
-    Also moved own includes to the top of files.
-    
-    Should be no functional changes :)
