#2219: sha512 compile issue on m32c/m32csim
---------------------------+-----------------------------

     Type:  defect         |     Status:  new
 Priority:  highest        |  Milestone:  4.11

 Severity:  blocker        |   Keywords:
---------------------------+-----------------------------
 The m32c has a 24 bit address space but only a 16 bit size_t. This results
 in it not being able to index large arrays. I suspect this is part of the
 problem with the failure in sha512. But the warnings indicate a more
 fundamental 16/32 bit coding issue.

 I propose the issue for the warnings get fixed and then sha512 disabled
 for m32c.
