Re: Need help diagnosing a z/OS compilation problem

Thanks for the info.  Having looked at this and looked at the code 
that's failing, it seems to me to be fairly easy to write a platform 
specific extension like there already is for platforms like android and 
darwin.  But I don't think I'm the one to do it.  If someone wants to 
tackle it, I'll commit their patch, but barring that, the first time 
someone really needs this functionality is when it will get written.  So 
I'm going to leave the test skipped.
