 - Bug Fixes:
     - Applied patch from Kito Cheng to update libopencl for checking NULL error
       code pointer. 
+    - Set the numeric locale before the parsing to a standard locale with the decimal point
+      represented as "dot" not a "comma", so parsing is done correctly independent of the
+      system locale.
 
 Version 3.2.0 versus 3.1.2
 - Added GPUWattch GPGPU power model based on McPAT 0.8beta.
