AFAICT upcoming Firebird 3.0 doesn't support MSVC 2015. Moreover,
following the discussion on FB developer mailing list, in this thread:
[1], it turns out, that MSVC 2013 was selected to be used for the next
FB 4 release, that tentatively expected to land in 2020 (info from the
mentioned thread). IOW, we can hope that FB > 4 will eventually support
MSVC 2015, something around 2025. Given that Python 3.5, that this
project currently depends on, dropped support for MSVC 2013, it could
be problematic to not being able to upgrade the tool chain on Windows
for the next 10 years.
