OK, I can see it. After some research, VS is, as usual, a pain to work with:
https://connect.microsoft.com/VisualStudio/feedback/details/1134693/vs-2015-ctp-5-c-vsnwprintf-s-and-other-functions-are-not-exported-in-appcrt140-dll-breaking-linkage-of-static-libraries
In this case it seems that __vsnwprintf_s is not DLL-exported, causing
the linking error. And a solution is to add
legacy_stdio_definitions.lib to fix that where odbccp32.lib is listed.
Like in the patch attached.
You could as well enforce the presence of this lib in CUSTOMLINKLIBS,
but I'd rather see win64.mak support natively the newest versions of
VS instead of the old ones.
