That's not how I read 18.4.1.  Quoting from n3092 (the most recent
draft I happen to have handy), 18.4.1/2 says

    The header defines all functions, types, and macros the same as
    7.18 in the C standard. [Note: The macros defined by <cstdint> are
    provided unconditionally.  In particular, the symbols
    __STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS (mentioned in
    footnotes 219, 220, and 222 in the C standard) play no role in
    C++. -- end note]

I read that as saying that macros such as WCHAR_MAX are always defined
by <cstdint>, irrespective of any definitions (or lack thereof) for
__STDC_LIMIT_MACROS.

That would be my reading too - note that C++03 lists these as required in 
table 95 - they're not new C++0x features.

None of which resolves the original question of course...
