Ah, great.  Thank you for checking with a later SDK.

There's probably no deeper reason why LibreOffice ended up using that 
specific SDK version for me.  (The code we use to configure paths for 
the various MSVC stuff is a bit "magic", and maybe that version was all 
that happened to be available on the machine I tested with.  I'll have a 
look.)
