Yes, it is in my CONFIG_SITE.win32-x86 I think.  There was a tech-talk
thread on this a while back.  The problem is that if you don't define
_WIN32_WINNT then it picks up a value from one of the Microsoft header
files, and that value may be for a recent Windows release (e.g. Windows
7).  If you use that value you can end up producing a .exe file that
will not run on the machine that built it!

I will apply that change, thanks.

Janet and I are trying to work out where your command-line flag 
/D_WIN32_WINNT=0x0503 is coming from because it's not a standard part of
Base.  
Is it from some site-specific configuration you've used?  We don't see
it 
ourselves on win32-x86 builds.
