Hi Les,

the lines you posted are compiler warnings, but not errors. That means 
that the build process should run through without trouble, or there is a 
real error further down the line.

These compiler warnings are there to notify you about possible (logic) 
mistakes in the code, but since they occur in the SWIG generated 
(PYTHON_wrap.cxx) code I suppose it will be very hard to fix them, so 
just ignore them.

Yours
Martin
