The patches can go anywhere.
They must be called from the main directory of the gimp source,
(the directory, containing 'configure.ac')
I use the .bat files - feel free to change the patches path and use it.

The .png-files must be copied in
themes/Default/images/tools 
otherwise the compile will fail.

The patches are for gimp-2.8.3 source from 15th nov 2012.
