[omniORB] CORBA::Double type corrouption issue in python omniORB

[Johnny Willemsen]

Hi,

Found the needed ARM documentation on the web. Looks TAO doesn't support 
the mixed endian double on ARM. Amit, I would recommend you to run the 
ACE tests/CDR_Array_Test on your target and see whether it works or not.

Best regards,
