No, it doesn't in this case.

Yaakov is talking about mingw-w64 headers used to create *Cygwin*
applications using the occasional Windows function.  Cygwin executables
in the distro run on Vista but not on XP or 2K3 anymore, given the
Cygwin DLL doesn't.

Therefore it might be a good idea to bump the default for these
Cygwin-related headers to at least 0x0600.

Setting them to 0x0602 sounds like a good idea, but as long as we didn't
drop Vista or W7 support it might be premature.

Btw., checking Cygwin sources for Vista and W7-specific code, it turned
out that actually very few lines of code handle Vista or W7-specific
workarounds.  The advantage of removing the code is pretty minor, so I
didn't push the changes.  While it's a bad idea to keep Vista and W7
running (at least attached to the internet), we can support them a while
longer.
