They seem plenty normative to me, or that has least been the intent.
The standard requires the presence and values
of a set of macros, and they affect the meaning of portable programs
written against a particular standard.

Sure, the phrasing in [version.syn]/1, "The header <version> supplies
implementation-dependent information
about the C ++ standard library (e.g.,version number and release
date)." is a bit funny, because there shouldn't
be anything implementation-dependent about the macros and their
values. Luckily, "implementation-dependent"
is not a Term of Power. :)
