Status of z/OS port

[Karl Williamson]

Perl now will compile and run on z/OS, requiring a couple of 
work-arounds to do so.  It fails our tests massively, and there are 
clearly a number of things wrong.  But I believe it is basically working 
except for Unicode and /i regular expression matching.  John and I are 
continuing to plug away at it.

Many of the tests are written so that no non-ASCII platform could 
succeed, so that its failing them badly is not indicative of how well it 
really works.
