Of course this doesn't help if the user project includes a headers that does
something inline with one of these calls. So for date-time I've wrapped up the
'deprecated calls in the following magic:

#if (defined(_MSC_VER) && (_MSC_VER >= 1400))
#pragma warning(push) // preserve warning settings
#pragma warning(disable : 4996) // disable deprecated localtime/gmtime warning
on vc8
#endif // _MSC_VER >= 1400
 
  //make the deprecated calls...

#if (defined(_MSC_VER) && (_MSC_VER >= 1400))
#pragma warning(pop) // restore warnings to previous state
#endif // _MSC_VER >= 1400

In date-time this is easy b/c all these calls are in about 20 lines of code. 
This solution silences both library and user build -- allowing the user to
decide on whether they want the warnings for their own code.

BTW, b/c builds on the HEAD with VC8 are really few and far between these
days, this change hasn't appeared in the regression results yet...

I suppose no matter the solution some documentation is in order.  What do you
think the odds are we can get Microsoft to write it ;-)
