Thanks for checking that. However, as that commit message says,
we require C99 support in v12 and up, and snprintf is definitely
required by C99. So I'm disinclined to revert that. If VS2013
can't supply snprintf, it's not meeting our minimum platform
standards, so we should remove it from the list of supported
platforms.
Having said that, Microsoft had had well over a dozen years by
that point to get off their duffs and build a C99-compliant
library. So I have to suspect that there is a snprintf lurking
somewhere --- maybe there is some build option you need to
enable to get it?
