That discussion is a bit confused between:

1) What will be used to compile the binaries on

2) What compiler or compiler*s* is/are supported and tested.

If 1) is MSVC2013 but 2) includes MSVC2015 (with developers regularly
using MSVC2015) then I wouldn't be that worried. Although some people
in that thread make that same point, I don't know of they are [core]
developers or outsiders, which would make a difference in the
impression it makes of the recognition by "the project" of these

IMHO 1) can even be switched between 4.0.5 and 4.0.6 or something like
that :) When Windows XP is "truly dead", even in the corners of
Northern Eurasia :)

Worrying indeed.

We could switch to not linking Firebird "in-house" but "just" bundling
it? The same way our predecessor project used to bundle Java (and
maybe other things)?

Would that seem workable to you guys? Assuming Firebird survives the
fact that Windows 18 will needs binaries compiled with MSVC 2030 or
something like that ;)
