From the viewpoint of perl not dropping the ebcdic support completely it
would be extremely important to get fresh and full results of make test,
using the published 5.16 if I have understood correctly. That would be
short term goal. Medium term would be to set up regular smoke testing, and
start hammering down the remaining issues.
