Might it be dependent on which VC++ package you have installed (or not) 
that determines which definition is used by Windows?

i.e. (from Hosoda-san)

I won't pretend to know the internals here but my work laptop has a 
number of different iterations of the older VC++ components installed, 
some of them go back to 2013 (for old internally made tools we still use 
now and again) and they seem to co-exist but I don't know what it is LP 
calls in this case. Some were installed manually and some by the various 
software installers I have run.

I don't know how or what Windows patches in this case.

Yours (probably getting it completely wrong).
