Not quite; the definition depends on the build toolset, not the build
platform. When building with VS 2015 and above, _WIN32_WINNT is set to
0x600 (Vista/2008), while with older compilers, the value is 0x501
(XP/2003). This is also due to locale issues, but of a different kind,
and is apparently coincidental.
The build platform does not figure into the target platform, which is
clearly a good idea for binary distribution reasons.
