Turn off VMS C's info about unsupported pragmas

VMS C can be notoriously informative about certain things, such as
unsupported pragmas.  The case here is that it doesn't support
"#pragma once", and since we use those quite a lot, that's a lot of
repeated information.  We simply turn that warning off.
