Hi John,

Thanks for the details. We'll rely on that.

OK. In gnulib we should talk about "OpenVMS". Just like we are talking about
Solaris, after it was renamed from SunOS by "the marketing people" of the
respective vendor. The Wikipedia article [1] also carries the title "OpenVMS".

Good point.

OK, then when we need to conditionalize, please remind us whether we should
use __CRTL_VER >= 80200000 or __CRTL_VER >= 80300000.
