There is some really strange behavior of Windows batch files where it 
sometimes fails with environment variables set with quotes and sometimes 
without...
Now I changed the line "SET LIBDIR=..\lib\win-i386" in run_example.cmd 
from quoted to non-quoted and for me it seems to work.

Any idea what might cause this erratic behavior?
