I think your reading of the standard is correct (and I did mean
__STDC_VERSION__, not _STDC_VER). I think the library is maintained as
part of the OS but the compiler is developed by a separate group that
maintains both the Tru64 and OpenVMS versions. The compiler should check
the library version and report its own standards level based on that,
but it apparently doesn't. This by way of explanation, not excuse.
