It was a matter of me misreading the error message. It says that
the specified compontent size 3 is not a factor of 8, rounding to a factor
... Which of read as rouding to a multiple of 8 (multiple/factor boy I
better run back to 2nd grade). 

Even still I think my original (modified by Robert) comment holds that while
the AdaMajic front end meets the requirements of the LRM it does the
minimum needed to meet those requirements in most areas (no support for
Ada 83 only attributes and pragmas) and limited support (although correct)
for rep specs.
