[1] is for Visual Studio 2005; Visual Studio 2010 also has 'safebuffers'
<http://msdn.microsoft.com/en-us/library/dabb5z75%28v=vs.100%29.aspx>.
If this latter is an exhaustive list, can we wrap each of these?
E.g., define __wrapped_align, __wrapped_allocate, __wrapped_appdomain,
etc. (I confess that I didn't follow the MSVC example you gave,
or why your simpler idea didn't work with MSVC.)
I notice that the corresponding section for C
<http://msdn.microsoft.com/en-us/library/k2f5w4h3.aspx>
doesn't list 'noreturn'.
Does __declspec(noreturn) work only with C++?
If so, then we need to worry about this issue only for C++.
Or is the C part of the documentation out-of-date?

Is this the complete list of MSVC include files that use
__declspec(noreturn)? If so, that might work too. But
it sounds more fragile than wrapping the list of __declspec
keywords.
Thanks for these ideas. If either of them work, I suppose
we can use them, but if there are problems with both of them
at least we have the simpler fallback of
"#define noreturn /* nothing */" on MSVC.
