Hi Orgad,

I still don't understand what problem this is trying to fix.  It looks 
like you want to make older versions of GDB work with newer versions of 
the Python scripts in the data directory.  I am not sure this is what we 
want.  If you want multiple version of GDB in parallel on a system, they 
should all be compiled with a different --prefix, and they will all get 
their own data-directory.  We should only expect a certain version of 
the data directory to be compatible with the version of GDB it was 
shipped with.  Or am I missing some use case where this is not true?
