Well the attached patch is significantly simplified once I got a handle on the 
casts. I have learned some things on this one. New patch is against trunk and 
includes the test cases.

Regression tested on x86-64 and test cases pass on big endian ppc64.  NIST 
tested.  ppc64 regression testing in progress.

As FX stated before, no need for the endian_off scheme.  No need for a macro as 
far as I can see.

OK for trunk?
